NAME
ALTER_TRIGGER - change the definition of a trigger
SYNOPSIS
ALTER TRIGGER \nname\n ON \ntable_name\n RENAME TO \nnew_name\n
ALTER TRIGGER \nname\n ON \ntable_name\n [ NO ] DEPENDS ON EXTENSION \nextension_nameDESCRIPTION
ALTER TRIGGER changes properties of an existing trigger.
The RENAME clause changes the name of the given trigger without otherwise changing the trigger definition. If the table that the trigger is on is a partitioned table, then corresponding clone triggers in the partitions are renamed too.
The DEPENDS ON EXTENSION clause marks the trigger as dependent on an extension, such that if the extension is dropped, the trigger will automatically be dropped as well.
You must own the table on which the trigger acts to be allowed to change its properties.
PARAMETERS
name
table_name
new_name
extension_name
NOTES
The ability to temporarily enable or disable a trigger is provided by ALTER TABLE, not by ALTER TRIGGER, because ALTER TRIGGER has no convenient way to express the option of enabling or disabling all of a table's triggers at once.
EXAMPLES
To rename an existing trigger:
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;To mark a trigger as being dependent on an extension:
ALTER TRIGGER emp_stamp ON emp DEPENDS ON EXTENSION emplib;COMPATIBILITY
ALTER TRIGGER is a PostgreSQL extension of the SQL standard.
