       CHECKPOINT - force a transaction log 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 Section 29.4, “WAL Configuration”, in the documentation 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 18.5.2, “Checkpoints”, in the documentation).  CHECKPOINT is not intended for use
       during normal operation.

       If executed during recovery, the CHECKPOINT command will force a restartpoint (see Section
       29.4, “WAL Configuration”, in the documentation) rather than writing a new checkpoint.

       Only superusers can call CHECKPOINT.


       The CHECKPOINT command is a PostgreSQL language extension.
