+.SH "NAME"
+CHECKPOINT \- force a write\-ahead log checkpoint
+.SH "SYNOPSIS"
+.sp
+.nf
+CHECKPOINT
+.fi
+.SH "DESCRIPTION"
+.PP
+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\ \&29.4
+for more details about what happens during a checkpoint\&.
+.PP
+The
+\fBCHECKPOINT\fR
+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\ \&19.5.2)\&.
+\fBCHECKPOINT\fR
+is not intended for use during normal operation\&.
+.PP
+If executed during recovery, the
+\fBCHECKPOINT\fR
+command will force a restartpoint (see
+Section\ \&29.4) rather than writing a new checkpoint\&.
+.PP
+Only superusers can call
+\fBCHECKPOINT\fR\&.
+.SH "COMPATIBILITY"
+.PP
+The
+\fBCHECKPOINT\fR
+command is a
+PostgreSQL
+language extension\&.
