    NAME

    CHECKPOINT - force a transaction log checkpoint
    

     

    SYNOPSIS

    CHECKPOINT
    
    
     

    DESCRIPTION

    Write-Ahead Logging (WAL) puts a checkpoint in the transaction log every so often. (To adjust the automatic checkpoint interval, see the run-time configuration options checkpoint_segments and checkpoint_timeout.) The CHECKPOINT command forces an immediate checkpoint when the command is issued, without waiting for a scheduled checkpoint.

    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 the documentation for more information about the WAL system.

    Only superusers may call CHECKPOINT. The command is not intended for use during normal operation.  

    COMPATIBILITY

    The CHECKPOINT command is a PostgreSQL language extension.
