Ensure parsing of queries in extension scripts sees the results of

immediately-preceding DDL (Julien Rouhaud, Tom Lane)
|

</para>

<para>

Due to lack of a cache flush step between commands in an extension

immediately preceding catalog change, such as <command>ALTER TABLE

</para>
|

|

<para>
|

The command failed if the calling user did not currently have

<literal>CREATE</> privilege for the tablespace containing the index.

That behavior seems unhelpful, so skip the check, allowing the

index to be rebuilt where it is.

</para>

<para>
|

This tended to lead to underestimation of the number of tuples in

the table. In the worst case of a small heavily-contended

contained no tuples, leading to very bad planning choices.

The IANA time zone database previously provided textual abbreviations
|

for all time zones, sometimes making up abbreviations that have little

or no currency among the local population. They are in process of
|
||||
reversing that policy in favor of using numeric UTC offsets in zones
|
||||
where there is no evidence of real-world use of an English
|
||||
abbreviation. At least for the time being, <productname>PostgreSQL</>
|
||||
will continue to accept such removed abbreviations for timestamp input.
|
||||
But they will not be shown in the <structname>pg_timezone_names</>
|

view nor used for output.

Use correct daylight-savings rules for POSIX-style time zone names
|
||||
in MSVC builds (David Rowley)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The Microsoft MSVC build scripts neglected to install
|
||||
the <filename>posixrules</> file in the timezone directory tree.
|
||||
This resulted in the timezone code falling back to its built-in
|
||||
rule about what DST behavior to assume for a POSIX-style time zone
|
||||
name. For historical reasons that still corresponds to the DST rules
|
||||
the USA was using before 2007 (i.e., change on first Sunday in April
|
||||
and last Sunday in October). With this fix, a POSIX-style zone name
|
||||
will use the current and historical DST transition dates of
|
||||
the <literal>US/Eastern</> zone. If you don't want that, remove
|
||||
the <filename>posixrules</> file, or replace it with a copy of some
|
||||
other zone file (see <xref linkend="datatype-timezones">). Note that
|
||||
due to caching, you may need to restart the server to get such changes
|
||||
to take effect.

Use correct daylight-savings rules for POSIX-style time zone names
|

in MSVC builds (David Rowley)
|

</para>
|

|
||||
<para>
|
||||
The Microsoft MSVC build scripts neglected to install
|
||||
the <filename>posixrules</> file in the timezone directory tree.
|
||||
This resulted in the timezone code falling back to its built-in
|
||||
rule about what DST behavior to assume for a POSIX-style time zone
|
||||
name. For historical reasons that still corresponds to the DST rules
|
||||
the USA was using before 2007 (i.e., change on first Sunday in April
|
||||
and last Sunday in October). With this fix, a POSIX-style zone name
|
||||
will use the current and historical DST transition dates of
|
||||
the <literal>US/Eastern</> zone. If you don't want that, remove
|
||||
the <filename>posixrules</> file, or replace it with a copy of some
|
||||
other zone file (see <xref linkend="datatype-timezones">). Note that
|
||||
due to caching, you may need to restart the server to get such changes
|
||||
to take effect.

Fix possibly-invalid initial snapshot during logical decoding
|
||||
(Petr Jelinek, Andres Freund)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The initial snapshot created for a logical decoding replication slot
|
||||
was potentially incorrect. This could cause third-party tools that
|
||||
use logical decoding to copy incomplete/inconsistent initial data.
|
||||
This was more likely to happen if the source server was busy at the
|
||||
time of slot creation, or if another logical slot already existed.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
If you are using a replication tool that depends on logical decoding,
|
||||
and it should have copied a nonempty data set at the start of
|
||||
replication, it is advisable to recreate the replica after
|
||||
installing this update, or to verify its contents against the source
|
||||
server.

This tended to lead to underestimation of the number of tuples in

The IANA time zone database previously provided textual abbreviations

for all time zones, sometimes making up abbreviations that have little

or no currency among the local population. They are in process of

reversing that policy in favor of using numeric UTC offsets in zones

where there is no evidence of real-world use of an English

abbreviation. At least for the time being, <productname>PostgreSQL</>
|

will continue to accept such removed abbreviations for timestamp input.

But they will not be shown in the <structname>pg_timezone_names</>

Use correct daylight-savings rules for POSIX-style time zone names
|

in MSVC builds (David Rowley)
|

</para>
|

|
||||
<para>
|
||||
The Microsoft MSVC build scripts neglected to install
|
||||
the <filename>posixrules</> file in the timezone directory tree.
|
||||
This resulted in the timezone code falling back to its built-in
|
||||
rule about what DST behavior to assume for a POSIX-style time zone
|
||||
name. For historical reasons that still corresponds to the DST rules
|
||||
the USA was using before 2007 (i.e., change on first Sunday in April
|
||||
and last Sunday in October). With this fix, a POSIX-style zone name
|
||||
will use the current and historical DST transition dates of
|
||||
the <literal>US/Eastern</> zone. If you don't want that, remove
|
||||
the <filename>posixrules</> file, or replace it with a copy of some
|
||||
other zone file (see <xref linkend="datatype-timezones">). Note that
|
||||
due to caching, you may need to restart the server to get such changes
|
||||
to take effect.

Fix possibly-invalid initial snapshot during logical decoding
|
||||
(Petr Jelinek, Andres Freund)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The initial snapshot created for a logical decoding replication slot
|
||||
was potentially incorrect. This could cause third-party tools that
|
||||
use logical decoding to copy incomplete/inconsistent initial data.
|
||||
This was more likely to happen if the source server was busy at the
|
||||
time of slot creation, or if another logical slot already existed.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
If you are using a replication tool that depends on logical decoding,
|
||||
and it should have copied a nonempty data set at the start of
|
||||
replication, it is advisable to recreate the replica after
|
||||
installing this update, or to verify its contents against the source
|
||||
server.

The IANA time zone database previously provided textual abbreviations
|
||||
for all time zones, sometimes making up abbreviations that have little
|
||||
or no currency among the local population. They are in process of
|
||||
reversing that policy in favor of using numeric UTC offsets in zones
|
||||
where there is no evidence of real-world use of an English
|
||||
abbreviation. At least for the time being, <productname>PostgreSQL</>
|
||||
will continue to accept such removed abbreviations for timestamp input.
|
||||
But they will not be shown in the <structname>pg_timezone_names</>
|
||||
view nor used for output.

Use correct daylight-savings rules for POSIX-style time zone names
|
||||
in MSVC builds (David Rowley)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The Microsoft MSVC build scripts neglected to install
|
||||
the <filename>posixrules</> file in the timezone directory tree.
|
||||
This resulted in the timezone code falling back to its built-in
|
||||
rule about what DST behavior to assume for a POSIX-style time zone
|
||||
name. For historical reasons that still corresponds to the DST rules
|
||||
the USA was using before 2007 (i.e., change on first Sunday in April
|
||||
and last Sunday in October). With this fix, a POSIX-style zone name
|
||||
will use the current and historical DST transition dates of
|
||||
the <literal>US/Eastern</> zone. If you don't want that, remove
|
||||
the <filename>posixrules</> file, or replace it with a copy of some
|
||||
other zone file (see <xref linkend="datatype-timezones">). Note that
|
||||
due to caching, you may need to restart the server to get such changes
|
||||
to take effect.

Fix possibly-invalid initial snapshot during logical decoding
|
||||
(Petr Jelinek, Andres Freund)
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The initial snapshot created for a logical decoding replication slot
|
||||
was potentially incorrect. This could cause third-party tools that
|
||||
use logical decoding to copy incomplete/inconsistent initial data.
|
||||
This was more likely to happen if the source server was busy at the
|
||||
time of slot creation, or if another logical slot already existed.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
If you are using a replication tool that depends on logical decoding,
|
||||
and it should have copied a nonempty data set at the start of
|
||||
replication, it is advisable to recreate the replica after
|
||||
installing this update, or to verify its contents against the source
|
||||
server.

There could be a significant delay (up to tens of seconds) before

satisfying a query's request for more than one worker process, or when

multiple queries requested workers simultaneously. On most platforms

this required unlucky timing, but on some it was the typical case.

Use correct daylight-savings rules for POSIX-style time zone names
|

in MSVC builds (David Rowley)
|

</para>
|
||||
|
||||
<para>
|
||||
The Microsoft MSVC build scripts neglected to install
|
||||
the <filename>posixrules</> file in the timezone directory tree.
|
||||
This resulted in the timezone code falling back to its built-in
|
||||
rule about what DST behavior to assume for a POSIX-style time zone
|
||||
name. For historical reasons that still corresponds to the DST rules
|
||||
the USA was using before 2007 (i.e., change on first Sunday in April
|
||||
and last Sunday in October). With this fix, a POSIX-style zone name
|
||||
will use the current and historical DST transition dates of
|
||||
the <literal>US/Eastern</> zone. If you don't want that, remove
|
||||
the <filename>posixrules</> file, or replace it with a copy of some
|
||||
other zone file (see <xref linkend="datatype-timezones">). Note that
|
||||
due to caching, you may need to restart the server to get such changes
|
||||
to take effect.
