NAME

       CHECKPOINT - force a transaction log checkpoint

SYNOPSIS

       CHECKPOINT

DESCRIPTION

       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.

COMPATIBILITY

       The CHECKPOINT command is a PostgreSQL language extension.
