Running the regression tests with -DCOPY_PARSE_PLAN_TREES reveals that DROP TRANSFORM parse trees fail to be copiable:
regression=# DROP TRANSFORM IF EXISTS FOR fake_type LANGUAGE plperl; ERROR: unrecognized node type: 1701866608 I've not tracked down the exact reason, but it kinda looks like the "argument" field has been filled with a list of bare C strings, not a list of String nodes which is what it'd have to be to work here. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
