29e132f5e9 PostgreSQL 12 support.
Recovery settings are now written into postgresql.auto.conf instead of recovery.conf.  Existing recovery_target* settings will be commented out to help avoid conflicts.

A comment is added before recovery settings to identify them as written by pgBackRest since it is unclear how, in general, old settings will be removed.

recovery.signal and standby.signal are automatically created based on the recovery settings.

3d3003e9ca The check command is implemented partly in C.
Implement switch WAL and archive check in C but leave the rest in Perl for now.

The main idea was to have some real integration tests for the new database code so the rest of the migration can wait.

d8ca0e5c5b Add Perl interface to C PgQuery object.
This validates that all current queries work with the new interface and removes the dependency on DBD::Pg.

0efdf2576f Remove hard-coded PostgreSQL user so $PGUSER works.
The PostgreSQL user was hard-coded to the OS user which libpq will automatically use if $PGUSER is not set, so this code was redundant and prevented $PGUSER from working when set.

6e88f93991 Fix check for improperly configured pg-path.
The check to verify that pg-path and data_directory are equal was not working because pg-path was getting overwritten with data_directory before validation took place.

286f7e5011 Fix static WAL segment size used to determine if archive-push-queue-max has been exceeded.
This calculation was missed when the WAL segment size was made dynamic in preparation for PostgreSQL 11.

Fix the calculation by checking the actual WAL file sizes instead of using an estimate based on WAL segment size.  This is more accurate because it takes into account .history and .backup files, which are smaller.  Since the calculation is done in the async process the additional processing time should not adversely affect performance.

Remove the PG_WAL_SIZE constant and instead use local constants where the old value is still required.  This is only the case for some tests and PostgreSQL 8.3 which does not provide a way to get the WAL segment size from pg_control.

d038b9a029 Support configurable WAL segment size.
PostgreSQL 11 introduces configurable WAL segment sizes, from 1MB to 1GB.

There are two areas that needed to be updated to support this: building the archive-get queue and checking that WAL has been archived after a backup.  Both operations require the WAL segment size to properly build a list.

Checking the archive after a backup is still implemented in Perl and has an active database connection, so just get the WAL segment size from the database.

The archive-get command does not have a connection to the database, so get the WAL segment size from pg_control instead.  This requires a deeper inspection of pg_control than has been done in the past, so it seemed best to copy the relevant data structures from each version of PostgreSQL and build a generic interface layer to address them.  While this approach is a bit verbose, it has the advantage of being relatively simple, and can easily be updated for new versions of PostgreSQL.

Since the integration tests generate pg_control files for testing, teach Perl how to generate files with the correct offsets for both 32-bit and 64-bit architectures.

36a5349b1c Added the --checksum-page option.
This option allows pgBackRest to validate page checksums in data files when checksums are enabled on PostgreSQL >= 9.3. Note that this functionality requires a C library which may not initially be available in OS packages. The option will automatically be enabled when the library is present and checksums are enabled on the cluster.

23a3911830 Stop using pg_xlogfile_name().
The pg_xlogfile_name() function is no longer used to construct WAL filenames from LSNs. While this function is convenient it is not available on a standby. Instead, the archive is searched for the LSN in order to find the timeline. If due to some misadventure the LSN appears on multiple timelines then an error will be thrown, whereas before this condition would have passed unnoticed.
