.SH "DESCRIPTION"
.PP
\fBALTER TRIGGER\fR changes properties of an existing
trigger. The RENAME clause changes the name of
the given trigger without otherwise changing the trigger

.SH "PARAMETERS"
.TP
\fB\fIname\fB\fR
The name of an existing trigger to alter.

\fB\fItable\fB\fR
The name of the table on which this trigger acts.

\fB\fInewname\fB\fR
The new name for the trigger.
.SH "NOTES"
.PP
The ability to temporarily enable or disable a trigger is provided by
ALTER TABLE [\fBalter_table\fR(7)], not by
\fBALTER TRIGGER\fR, because \fBALTER TRIGGER\fR has no
convenient way to express the option of enabling or disabling all of
a table's triggers at once.
.SH "EXAMPLES"
.PP
To rename an existing trigger:
.sp
.nf
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;
.sp
.fi
.SH "COMPATIBILITY"

\fBALTER TRIGGER\fR is a PostgreSQL
extension of the SQL standard.
