A read-only preset, like block_size — SHOW data_checksums tells you whether the cluster has page checksums, and that’s the only interaction the GUC offers. But
The planner assumes cursors fetch only 10% of results by default. If you're actually reading them all, that fast-start bias could be killing your performance.
Azure's managed PostgreSQL differs from competitors by putting the standby in the commit path—every write waits for synchronous replication to a second server…
cpu_tuple_cost, cpu_index_tuple_cost, and cpu_operator_cost are three of the constants the planner uses to price a query, and the single most useful thing to kn
PostgreSQL's `config_file` parameter creates a bootstrap paradox: it tells the server where to find its configuration, but lives on the command line only—never…

PostgreSQL 16 overhauled role management to tame the near-superuser power of CREATEROLE.

PostgreSQL 19 adds GRAPH_TABLE, letting you query property graphs with Cypher-like pattern matching over your existing relational tables.
Skip partition scanning with constraint_exclusion, PostgreSQL's old pruning trick.

PostgreSQL 14 unified query-id computation across all subsystems, but defaulting to always-on would tax every backend.
