NAME

6       CHECKPOINT - force a write-ahead log checkpoint
7

SYNOPSIS

9       CHECKPOINT
10

DESCRIPTION

12       A checkpoint is a point in the write-ahead log sequence at which all
13       data files have been updated to reflect the information in the log. All
14       data files will be flushed to disk. Refer to Section 29.4 for more
15       details about what happens during a checkpoint.
16
17       The CHECKPOINT command forces an immediate checkpoint when the command
18       is issued, without waiting for a regular checkpoint scheduled by the
19       system (controlled by the settings in Section 19.5.2).  CHECKPOINT is
20       not intended for use during normal operation.
21
22       If executed during recovery, the CHECKPOINT command will force a
23       restartpoint (see Section 29.4) rather than writing a new checkpoint.
24
25       Only superusers can call CHECKPOINT.
26

COMPATIBILITY

28       The CHECKPOINT command is a PostgreSQL language extension.
