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There are two areas that needed to be updated to support this: building the archive-get queue and checking that WAL has been archived after a backup.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. 2018-09-25 10:24:42 +01:00			`/***********************************************************************************************************************************`
