commit 91d1f2d302108f49006eedb8053522236dde77cc
Author: Peter Eisentraut <peter@eisentraut.org>
Date: Thu Mar 25 09:06:32 2021 +0000
First released in: 14.0
Rename a parse node to be more general
A WHERE clause will be used for row filtering in logical replication.
We already have a similar node: 'WHERE (condition here)'. Let's
rename the node to a generic name and use it for row filtering too.
