CHECKPOINT(7) SQL Commands CHECKPOINT(7)NAME
CHECKPOINT - force a transaction log checkpoint
SYNOPSIS
CHECKPOINT
DESCRIPTION
Write-Ahead Logging (WAL) puts a checkpoint in the transaction log every so often. (To adjust the automatic checkpoint interval, see the
run-time configuration options checkpoint_segments and checkpoint_timeout.) The CHECKPOINT command forces an immediate checkpoint when the
command is issued, without waiting for a scheduled checkpoint.
A checkpoint is a point in the transaction log sequence at which all data files have been updated to reflect the information in the log.
All data files will be flushed to disk. Refer to in the documentation for more information about the WAL system.
Only superusers can call CHECKPOINT. The command is not intended for use during normal operation.
COMPATIBILITY
The CHECKPOINT command is a PostgreSQL language extension.
