Обсуждение: Dropping a type

<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">I'm using pgAdmin 1.12.3 on Mac OSx.  I
havefunctions that use a Type rowtype to hold the results of a query.  When I change the query to add/remove columns, I
alsochange the Type, then do a drop, then create, and get a success message.  However, I then need to drop and create
alldependent objects, including functions.  If I don't, users will get an error.  Refreshing the database in pgAdmin
showsthe type has indeed changed, but users will still get an error until I drop and create the affected object
(function).<br/><br /> Earlier versions of pgAdmin would give an error when dropping a Type, letting me know what
objectswere dependent on that Type.  I would then do the drop with cascade, then create the function(s) affected.<br

I'm sure I understand your issue. IIUC, this seems more an issue with
PostgreSQL than pgAdmin. If I'm wrong, can you supply a small test case?
