Subject: pgsql: doc: clarify MERGE PARTITIONS adjacency requirement
Date: Tue, 30 Jun 2026 19:36:18 +0000
Message-ID: <E1weeFn-000oR5-0Q@gemulon.postgresql.org> (raw)
doc: clarify MERGE PARTITIONS adjacency requirement
The existing description says the ranges of merged range-partitions
"must be adjacent" only under the heading "If the DEFAULT partition is
not in the list of merged partitions". That could be misread as
a restriction tied to the presence of a default partition. In fact,
merging non-adjacent ranges is rejected regardless of whether
the partitioned table has a default partition; spell that out explicitly.
Also, this commit removes a small redundancy in the documentation sentence
stating that "merged range-partitions" are "to be merged".
