4741e9afb93f0d769655b2d18c2b73b86f281010. This was done by adding an
optional second log file parameter to exec_prog(), and closing and
reopening the log file between system() calls.
Backpatch to 9.2.
Since the scandir() emulation was taken out of pg_upgrade, there's
no longer any need for scandir_file_pattern to exist as a global
variable. Replace it with a local in the one remaining function
that was making use of it.
Error out on out-of-memory, rather than returning -1, which the sole
existing caller wasn't checking for anyway. There doesn't seem to be
any use-case for making the caller check for failure here.
Detect failure return from readdir().
Use a less platform-dependent method of calculating the entrysize.
It's possible, but not yet confirmed, that this explains bug #6733,
in which Mike Wilson reports a pg_upgrade crash that did not occur
in 9.1. (Note that load_directory is effectively new code in 9.2,
at least on platforms that have scandir().)
Fix up comments, avoid uselessly using two counters, reduce the number
of realloc calls to something sane.
default tablespace, but part of a database that is in a user-defined
tablespace. Caused "file not found" error during upgrade.
Per bug report from Ants Aasma.
Backpatch to 9.1 and 9.0.
add ability to control permissions of created files
have psql echo its queries for easier debugging
output four separate log files, and delete them on success
add -r/--retain option to keep log files after success
make logs file append-only
remove -g/-G/-l logging options
sugggest tailing appropriate log file on failure
enhance -v/--verbose behavior
Add __attribute__ decorations for printf format checking to the places that
were missing them. Fix the resulting warnings. Add
-Wmissing-format-attribute to the standard set of warnings for GCC, so these
don't happen again.
The warning fixes here are relatively harmless. The one serious problem
discovered by this was already committed earlier in
cf15fb5cabfbc71e07be23cfbc813daee6c5014f.
the connection; also restructure the libpq connection code.
This patch also removes the unused variable postmasterPID and fixes a
libpq structure leak that was in the testing loop.
This option turns off autovacuum, prevents non-super-user connections,
and enables oid setting hooks in the backend. The code continues to use
the old autoavacuum disable settings for servers with earlier catalog
versions.
This includes a catalog version bump to identify servers that support
the -b option.
up relations, but rather order old/new relations and use the same array
index value for both. This should speed up pg_upgrade for databases
with many relations.
which is stored in pg_largeobject_metadata.
No backpatch to 9.0 because you can't migrate from 9.0 to 9.0 with the
same catversion (because of tablespace conflict), and a pre-9.0
migration to 9.0 has not large object permissions to migrate.
Toast tables have identical pg_class.oid and pg_class.relfilenode, but
for clarity it is good to preserve the pg_class.oid.
Update comments regarding what is preserved, and do some
variable/function renaming for clarity.
pointers, which simplifies the code. This was not possible in 9.0 because
everything was in a single nested struct, but is possible now.
Per suggestion from Tom.
