NAME

6       CHECKPOINT - force a transaction log checkpoint
7

SYNOPSIS

9       CHECKPOINT
10

DESCRIPTION

12       A checkpoint is a point in the transaction 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, “WAL
15       Configuration”, in the documentation for more details about what
16       happens during a checkpoint.
17
18       The CHECKPOINT command forces an immediate checkpoint when the command
19       is issued, without waiting for a regular checkpoint scheduled by the
20       system (controlled by the settings in Section 18.5.2, “Checkpoints”, in
21       the documentation).  CHECKPOINT is not intended for use during normal
22       operation.
23
24       If executed during recovery, the CHECKPOINT command will force a
25       restartpoint (see Section 29.4, “WAL Configuration”, in the
26       documentation) rather than writing a new checkpoint.
27
28       Only superusers can call CHECKPOINT.

COMPATIBILITY

31       The CHECKPOINT command is a PostgreSQL language extension.
