CHECKPOINT(7) PostgreSQL 10.1 Documentation CHECKPOINT(7)NAMECHECKPOINT - force a write-ahead log checkpoint
SYNOPSISCHECKPOINTDESCRIPTION
A checkpoint is a point in the write-ahead 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 Section 30.4 for more
details about what happens during a checkpoint.
The CHECKPOINT command forces an immediate checkpoint when the command
is issued, without waiting for a regular checkpoint scheduled by the
system (controlled by the settings in Section 19.5.2). CHECKPOINT is
not intended for use during normal operation.
If executed during recovery, the CHECKPOINT command will force a
restartpoint (see Section 30.4) rather than writing a new checkpoint.
Only superusers can call CHECKPOINT.
COMPATIBILITY
The CHECKPOINT command is a PostgreSQL language extension.
