According to the WAL config documentation correctly, checkpoints are created every <mk:@MSITStore:C:\Program%20Files\PostgreSQL\8.2\pgAdmin%20III\docs\en_US\pg admin3.chm::/pg/runtime-config-wal.html#guc-checkpoint-segments> checkpoint_segments log segments, or every <mk:@MSITStore:C:\Program%20Files\PostgreSQL\8.2\pgAdmin%20III\docs\en_US\pg admin3.chm::/pg/runtime-config-wal.html#guc-checkpoint-timeout> checkpoint_timeout seconds, whichever comes first. However, it seems as though setting my checkpoint_timeout has no effect on checkpoint creation ( I have it set to 30 seconds). Forcing checkpoint by running psql -c CHECKPOINT mydb doesn't do the trick either. Checkpoints are created solely based on the checkpoint_segments logs reaching their configured size.
This is not satisfactory in a low transaction volume environment. Any hints on how else can I trigger checkpoint? Thanks in advance, ~george
