Hi,
The Windows tests are failing on `Assert("check_GUC_init(hentry->gucvar)")` for wal_writer_flush_after [1]. It doesn't make much sense to me as both load- and C-value for the wal_writer_flush_after GUC are the same constant:
src/backend/utils/misc/guc_parameters.dat:
{ name => 'wal_writer_flush_after', type => 'int', context => 'PGC_SIGHUP', group => 'WAL_SETTINGS',
short_desc => 'Amount of WAL written out by WAL writer that triggers a flush.',
flags => 'GUC_UNIT_XBLOCKS',
variable => 'WalWriterFlushAfter',
boot_val => 'DEFAULT_WAL_WRITER_FLUSH_AFTER',
min => '0',
max => 'INT_MAX',
},
src/include/postmaster/walwriter.h:
int WalWriterFlushAfter = DEFAULT_WAL_WRITER_FLUSH_AFTER;
This constant was introduced to fix the same issue [2], but I suppose no one checked Windows builds. Windows clearly has an old 8kB value for WalWriterFlushAfter during the check. I suppose it is something with the CI/build. But I have zero experience with building anything for Windows, so any tips on where to look are welcome.
*And apologies for the dreadful formatting in my previous email; the client plays tricks on me after I hit Send.
