Use the Name edit box to set the trigger name. This must be distinct from the name of any other trigger for the same table.
Row trigger
This specifies whether the trigger procedure should be fired once for every row affected by the
trigger event, or just once per SQL statement. If unchecks, FOR EACH STATEMENT is the default.
Trigger Function Schema and Trigger Function
A user-supplied function that is declared as taking no arguments and returning
type trigger, which is executed when the trigger fires.
Arguments
An optional comma-separated list of arguments to be provided to the function
when the trigger is executed. The arguments are literal string constants.
Simple names and numeric constants may be written here, too, but they will
all be converted to strings. Please check the description of the implementation
language of the trigger function about how the trigger arguments are accessible
within the function; it may be different from normal function arguments.
The Comment edit box defines the comment for the trigger.
