mainloop.c. This ensures that postgres_fe.h is read before including
any system headers, which is necessary to avoid problems on some platforms
where we make nondefault selections of feature macros for stdio.h or
other headers. We have had this policy for flex modules in the backend
for many years, but for some reason it was not applied to psql.
Per trouble report from Alexandra Roy and diagnosis by Albe Laurenz.
(could happen if either postgresql.conf or postmaster.opts is empty).
It's been broken since the C version was written for 8.0, so patch
all the way back.
initdb's copy of the function is broken in the same way, but it's
less important there since the input files should never be empty.
Patch that in HEAD only, and also fix some cosmetic differences that
crept into that copy of the function.
Per report from Corry Haines and Jeff Davis.
#include the version of history.h that is in the same directory as the
readline.h we are using. This avoids problems in some scenarios where both
readline and editline are installed. Report and patch by Zdenek Kotala.
when we reach the post-COPY "pump it dry" error recovery code that was added
2006-11-24. Per a report from Neil Best, there is at least one code path
in which this occurs, leading to an infinite loop in code that's supposed
to be making it more robust not less so. A reasonable response seems to be
to call PQputCopyEnd() again, so let's try that.
Back-patch to all versions that contain the cleanup loop.
It's not possible to do CREATE DATABASE inside a transaction, so previously
we just got a server error instead.
Backpatch to 8.2, which is where the -1 feature appeared.
returns NULL instead of a PGresult. The former coding would fail, which
is OK, but it neglected to give you the PQerrorMessage that might tell
you why. In the oldest branches, there was another problem: it'd sometimes
report PQerrorMessage from the wrong connection.
by explicitly adding back the user to the DACL of the new process.
This fixes the failure case when executing as the Administrator
user, which had no permissions left at all after we dropped the
Administrators group.

non-default settings for the postmaster's port number. The code to parse
command line options and postgresql.conf entries wasn't quite right about
whitespace or quotes, and it was coded in a not-very-readable way too.
Per bug #3969 from Itagaki Takahiro, though this is more extensive than his
proposed patch (which fixed only the whitespace problem).
This code has been broken since it was put in in 8.0, so patch all the way
back.
that have default expressions different from their parent. First, if the
parent table's default expression has to be split out as a separate
ALTER TABLE command, we need a dependency constraint to ensure that the
child's command is given second. This is because the ALTER TABLE on the
parent will propagate to the child. (We can't prevent that by using ONLY on
the parent's command, since it's possible that other children exist that
should receive the inherited default.) Second, if the child has a NULL
default where the parent does not, we have to explicitly say DEFAULT NULL on
the child in order for this state to be preserved after reload. (The latter
actually doesn't work right because of a backend bug, but that is a separate
issue.)
Backpatch as far as 8.0. 7.x pg_dump has enough issues with altered tables
(due to lack of dependency analysis) that trying to fix this one doesn't seem
very productive.
read from the temp file didn't match the file length reported by ftello(),
the wrong variable's value was printed, and so the message made no sense.
Clean up a couple other coding infelicities while at it.
output after each FETCH. This ensures that incremental results are
available to clients that are executing long-running SELECT queries
via the FETCH_COUNT feature.
sequence for dumping without also selecting its owning table. Make it not try
to emit ALTER SEQUENCE OWNED BY in this situation.
Per report from Michael Nolan.
database privileges from a pre-8.2 server. This ensures that the reloaded
database will maintain the same behavior it had in the previous installation,
ie, everybody has connect privilege. Per gripe from L Bayuk.
PQdsplen()) normally, instead of replacing them by \uXXXX sequences.
Assume that they in fact occupy zero screen space for formatting purposes.
Per gripe from Michael Fuhr and ensuing discussion.
(in particular, causing the ReadyForQuery message to be eaten) before
returning from do_copy. The only known consequence of failing to do so is
that get_prompt might show a wrong result for the %x transaction status
escape, as reported by Bernd Helmle; but it's possible there are other issues.
Back-patch as far as 7.4, the oldest version supporting %x.
because on that platform strftime produces localized zone names in varying
encodings. Even though it's only in a comment, this can cause encoding
errors when reloading the dump script. Per suggestion from Andreas
Seltenreich. Also, suppress %Z on Windows in the %s escape of
log_line_prefix ... not sure why this one is different from the other two,
but it shouldn't be.
(blobs) with comments, per bug #2727 from Konstantin Pelepelin.
Mea culpa for not having tested this case.
Back-patch to 8.1; prior branches don't dump blob comments at all.
