CHECKPOINT(7)           PostgreSQL 9.5.0 Documentation           CHECKPOINT(7)

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.
