CHECKPOINT(7)

💖 CHECKPOINT 💖

okay so bestie, welcome to the CHECKPOINT(7) page — manual section 7, PostgreSQL girlie edition. we're talking about forcing a write-ahead log checkpoint, and yes it's giving main character energy for your WAL. 💅

🌸 NAME 🌸

CHECKPOINT — force a write-ahead log checkpoint. literally that's the whole vibe: you tell it “checkpoint now,” and it does.

✨ SYNOPSIS ✨

CHECKPOINT

💅 DESCRIPTION 💅

okay so picture this: a checkpoint is a point in the write-ahead log sequence where, like, all the data files have been updated to reflect the info in the log. all data files get flushed to disk. if you want the full lore on what goes down during a checkpoint, refer to Section 30.5. ✨

the CHECKPOINT command forces an immediate checkpoint the moment you issue it — no waiting around for the regular checkpoint the system scheduled (that one's controlled by the settings in Section 20.5.2). but bestie, hear me: CHECKPOINT is not intended for use during normal operation. it's a “when you need it” move, not a daily habit. 🫶

if you run it during recovery, the CHECKPOINT command will force a restartpoint (see Section 30.5) instead of writing a new checkpoint. iykyk. 🦋

and the access check? only superusers or users with the privileges of the pg_checkpoint role can call CHECKPOINT. no random group-chat members getting in. 👑

🦋 COMPATIBILITY 🦋

the CHECKPOINT command is a PostgreSQL language extension. periodt.

mwah 💋 that's the whole page, bestie. this one's from the PostgreSQL 15.19 documentation, dated 2026 — go forth and checkpoint responsibly. 🎀
