Subject: pgsql: Remove the query_id_squash_values GUC
Date: Thu, 27 Mar 2025 12:37:55 +0000
Message-ID: <[email protected]> (raw)
Remove the query_id_squash_values GUC
Commit 62d712ecfd94 introduced the capability to calculate the same
queryId for queries with different lengths of constants in a list for an
IN clause. This behavior was originally enabled with a GUC
query_id_squash_values. After a discussion about the value of such a
GUC, it was decided to back out of the use of a GUC and make the
squashing behavior the only available option.
