\watch

Repeatedly execute the current query buffer (as \g does) until interrupted, or the query fails, or the execution count limit (if given) is reached, or the query no longer returns the minimum number of rows. Wait the specified number of seconds (default 2) between executions. The default wait can be changed with the variable WATCH_INTERVAL . For backwards compatibility, seconds can be specified with or without an interval= prefix. Each query result is displayed with a header that includes the \pset title string (if any), the time as of query start, and the delay interval.

\watch [ i[nterval]=seconds ] [ c[ount]=times ] [ m[in_rows]=rows ] [ seconds ]

Repeatedly execute the current query buffer (as \g does) until interrupted, or the query fails, or the execution count limit (if given) is reached, or the query no longer returns the minimum number of rows. Wait the specified number of seconds (default 2) between executions. The default wait can be changed with the variable WATCH_INTERVAL. For backwards compatibility, seconds can be specified with or without an interval= prefix. Each query result is displayed with a header that includes the \pset title string (if any), the time as of query start, and the delay interval.

If the current query buffer is empty, the most recently sent query is re-executed instead.
