Even though this only affects the insertion of a parenthesized word,
it's unwise to assume that parentheses can pass through untranslated.
And in any case, the new version is clearer in the code and for
translators.
The code to assemble ldap_get_values_len's output into a single string
wrote the terminating null one byte past where it should. Fix that,
and make some other cosmetic adjustments to make the code a trifle more
readable and more in line with usual Postgres coding style.
Also, free the "result" string when done with it, to avoid a permanent
memory leak.
Bug report and patch by Albe Laurenz, cosmetic adjustments by me.
Normally nel == 0 works okay because the initial value of "last" will be
less than "base"; but if "base" is zero then the calculation wraps around
and we have a very large (unsigned) value for "last", so that the loop can
be entered and we get a SIGSEGV on a bogus pointer.
This is certainly the proximate cause of the recent reports of Windows
builds crashing on 'infinity'::timestamp --- evidently, they're either not
setting an active timezonetktbl, or setting an empty one. It's not yet
clear to me why it's only happening on Windows and not happening on any
buildfarm member. But even if that's due to some bug elsewhere, it seems
wise for this function to not choke on the powerup values of
timezonetktbl/sztimezonetktbl.
I also changed the copy of this code in ecpglib, although I am not sure
whether it's exposed to a similar hazard.
Per report and stack trace from Richard Broersma.
Per recent -hackers discussion. The formats in question are %G and %V,
and cause warnings on MinGW at least. We assume the ecpg application
knows what it's doing if it passes these formats to the library.
The style is set to "printf" for backwards compatibility everywhere except
on Windows, where it is set to "gnu_printf", which eliminates hundreds of
false error messages from modern versions of gcc arising from %m and %ll{d,u}
formats.
The recent patch to remove gcc 4.6 warnings created some new ones, at
least on my rather old gcc version. Try to make everybody happy by
casting to "void" when we just want to discard the result.
This warning is new in gcc 4.6 and part of -Wall. This patch cleans
up most of the noise, but there are some still warnings that are
trickier to remove.
This would lead to leaking the PGconn structure after an error detected by
conninfo_array_parse(), as well as failing to return a useful error message
in such cases. Backpatch to 9.0 where the error was introduced.

variable hiding. A constant is not a variable. It worked in most cases by
accident, because we add constants to the global list of variables (why?),
but float constants like 1.23 were interpreted as struct field references,
and not found.
Backpatch to 9.0, where the test for variable hiding was added.
In addition to the
all-foo-recurse: all-bar-recurse
dependencies that constraint the order of the rule execution, we need
install-foo-recurse: install-bar-recurse
dependencies in case one runs make install without a make all first,
as some people apparently do.
Instead, just act as though the certificate file(s) are not present.
There is only one case where this need be a hard failure condition: when
sslmode is verify-ca or verify-full, not having a root cert file is an
error. Change the logic so that we complain only in that case, and
otherwise fall through cleanly. This is how it used to behave pre-9.0,
but my patch 4ed4b6c54e of 2010-05-26 broke
the case. Per report from Christian Kastner.
Add a new libpq connection option client_encoding (which includes the
existing PGCLIENTENCODING environment variable), which besides an
encoding name accepts a special value "auto" that tries to determine
the encoding from the locale in the client's environment, using the
mechanisms that have been in use in initdb.
psql sets this new connection option to "auto" when running from a
terminal and not overridden by setting PGCLIENTENCODING.

Recent releases had a check on rel->rd_refcnt in heap_drop_with_catalog,
but failed to cover the possibility of pending trigger events at DROP time.
(Before 8.4 we didn't even check the refcnt.) When the trigger events were
eventually fired, you'd get "could not open relation with OID nnn" errors,
as in recent report from strk. Better to throw a suitable error when the
DROP is attempted.
Also add a similar check in DROP INDEX.
Back-patch to all supported branches.
string". This is not really needed because the string gets copied to the output
untranslated anyway, but by adding this rule the lexer stays in sync with the
backend lexer.
This function is like the PQserverVersion() function except
it returns the version of libpq, making it possible for a client
program or driver to determine which version of libpq is in
use at runtime, and not just at link time.
Suggested by Harald Armin Massa and several others.
libpq connection, per report from Magnus. This happens only on GIT
master and only on Win32 because that is the platform where "" maps to
an IP address (localhost).
Basically, we want to distinguish all cases where the connection was
not made from those where it was. A convenient proxy for this is to
see if we got a message with a SQLSTATE code back from the postmaster.
This presumes that the postmaster will always send us a SQLSTATE in
a failure message, which is true for 7.4 and later postmasters in
every case except fork failure. (We could possibly complicate the
postmaster code to do something about that, but it seems not worth
the trouble, especially since pg_ctl's response for that case should
be to keep waiting anyway.)
If we did get a SQLSTATE from the postmaster, there are basically only
two cases, as per last week's discussion: ERRCODE_CANNOT_CONNECT_NOW
and everything else. Any other error code implies that the postmaster
is in principle willing to accept connections, it just didn't like or
couldn't handle this particular request. We want to make a special
case for ERRCODE_CANNOT_CONNECT_NOW so that "pg_ctl start -w" knows
it should keep waiting.
In passing, pick names for the enum constants that are a tad less
likely to present collision hazards in future.
status, including a status where the server is running but refuses a
postgres connection.
Have pg_ctl use this new function. This fixes the case where pg_ctl
reports that the server is not running (cannot connect) but in fact it
is running.
