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.

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.
supplied, also print the IP address. This allows IPv4 and IPv6 failures
to be distinguished. Also useful when a hostname resolves to multiple
IP addresses.
Also, remove use of inet_ntoa() and use our own inet_net_ntop() in all
places, including in libpq, because it is thread-safe.
Add some additional dependencies to constrain the build order to prevent
parallel make from failing. In the case of src/Makefile, this is likely to be
too complicated to be worth maintaining, so just add .NOTPARALLEL to get the
old for-loop-like behavior.
More fine-tuning might be necessary for some platforms or configurations.
Replace for loops in makefiles with proper dependencies. Parallel
make can now span across directories. Also, make -k and make -q work
properly.
GNU make 3.80 or newer is now required.
Use bool as type for booleans instead of int.
Do not implicitely cast size_t to int.
Make the compiler stop complaining about unused variables by adding an empty statement.
The trick is to not try to build executables directly from .c files,
but to always build the intermediate .o files. For obscure reasons,
Darwin's version of gcc will leave debug cruft behind in the first
case but not the second. Per complaint from Robert Haas.
ecpglib. Instead of parsing the statement just as ask the database server. This
patch removes the whole client side track keeping of the current transaction
status.
The previous patches failed to cover a lot of symlinks that are only
added in platform-specific cases. Make the lists match what's in the
Makefile for each branch.
