Fix interaction between CREATE INDEX and "snapshot too old".
Since indexes are created without valid LSNs, an index created
while a snapshot older than old_snapshot_threshold existed could
cause queries to return incorrect results when those old snapshots
were used, if any relevant rows had been s

Since vacuum calls the pruning function, and not the other way
around, the name you suggest would be tech
Schema-qualify some references to regprocedure.

Update pg_stat_statements extension for parallel query.
All functions provided by this extension are PARALLEL SAFE. Given the
general prohibition against write operations in parallel queries, it is
perhaps a bit surprising that pg_stat_statements_reset() is parallel safe.
But since it only modifi

Refactor to reduce code duplication for function property checking.
As noted by Andres Freund, we'd accumulated quite a few similar functions
in clauses.c that examine all functions in an expression tree to see if
they satisfy some boolean test. Reduce the duplication by inventing a
function chec
Remove reltarget_has_non_vars flag.
Commit b12fd41c6 added a "reltarget_has_non_vars" field to RelOptInfo,
but failed to maintain it accurately. Since its only purpose was to skip
calls to has_parallel_hazard() in the simple case where a rel's targetlist
is all Vars, and that call is really prett
Change default of backend_flush_after GUC to 0 (disabled).
While beneficial, both for throughput and average/worst case latency, in
a significant number of workloads, there are other workloads in which
backend_flush_after can cause significant performance regressions in
