## NAME
       CHECKPOINT - force a write-ahead log checkpoint

## SYNOPSIS
       CHECKPOINT

## DESCRIPTION
       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 30.5 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 20.5.2).  **CHECKPOINT** is not intended for use during normal operation.

       If executed during recovery, the **CHECKPOINT** command will force a restartpoint (see
       Section 30.5) rather than writing a new checkpoint.

       Only superusers can call **CHECKPOINT**.

## COMPATIBILITY
       The **CHECKPOINT** command is a PostgreSQL language extension.
