socket location. Also, prevent putting the socket in the current
directory for pre-9.1 servers in live check and non-live check mode,
because pre-9.1 pg_ctl -w can't handle it.
Backpatch to 9.2.
pg_upgrade produces a platform-specific script to remove the old
directory, but on Windows it has not been making sure that the
paths it writes as arguments for rmdir and del use the backslash
path separator, which will cause these scripts to fail.
The fix is backpatched to Release 9.0.
When starting either an old or new postmaster, force it to place its Unix
socket in the current directory. This makes it even harder for accidental
connections to occur during pg_upgrade, and also works around some
scenarios where the default socket location isn't usable. (For example,
if the default location is something other than "/tmp", it might not exist
during "make check".)
When checking an already-running old postmaster, find out its actual socket
directory location from postmaster.pid, if possible. This dodges problems
with an old postmaster having a configured location different from the
default built into pg_upgrade's libpq. We can't find that out if the old
postmaster is pre-9.1, so also document how to cope with such scenarios
manually.
In support of this, centralize handling of the connection-related command
line options passed to pg_upgrade's subsidiary programs, such as pg_dump.
This should make future changes easier.

The previous signature made it very easy to pass something other than
the printf-format specifier in the corresponding position, without any
warning from the compiler.
While at it, move some of the escaping, redirecting and quoting
responsibilities from the callers into exec_prog() itself. This makes
the callsites cleaner.

optional second log file parameter to exec_prog(), and closing and
reopening the log file between system() calls.

for the pg_upgrade_support shared object, like we do for other shared
object checks.

There's no reason for this test to use the undocumented pg_prepared_xact()
function, when it can use the stable API pg_prepared_xacts instead.
Fixes breakage against 8.3, as reported by Justin Arnold.
Add errno-based output to error messages where appropriate, reformat
blocks to about 72 characters per line, use spaces instead of tabs for
indentation, and other style adjustments.
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.
If someone removes the 'postgres' database from the old cluster and the
new cluster has a 'postgres' database, the number of databases will not
match. We actually could upgrade such a setup, but it would violate the
1-to-1 mapping of database counts, so we throw an error instead.
Previously they got an error during the upgrade, and not at the check
stage; PG 9.0.4 does the same.
