Subject: pgsql: Add percentage of available IDs to wraparound warnings.
Date: Fri, 20 Mar 2026 19:16:30 +0000
Message-ID: <E1w3fKf-000gcR-1Q@gemulon.postgresql.org> (raw)
Add percentage of available IDs to wraparound warnings.
This commit adds DETAIL messages to the existing wraparound
WARNINGs that include the percentage of transaction/multixact IDs
that remain available for use. The hope is that this more clearly
expresses the urgency of the situation.
