[pgpool-general: 3561] Multiple active PGPool servers and Statement cache

[James Sewell]

Hey,

This is more of a feature request. Once of our clients uses PGPool
Active/Active, and they have an interest in using statement cache.

My understanding is that this will not work, as an update to PGPool a will
not invalidate PGPool b's cache object.

Would it be possible to implement the sharing of statement cache
invalidation via watchdog? Obviously this would be under the same proviso
that standard streaming replication is: that a PGPool node may be slightly
behind the other at any one time due to network lag.

Cheers,

James Sewell,
