Thanks Tom,
unfortunately running
create extension tsearch2 from unpackaged;
caused the following error:
ERROR: operator family "gist_tsvector_ops" does not exist for access
method "gist"
So I think I will have to create a script to delete the functions etc
individually unless someone has another idea.
For the tables that contain tsvector columns, is it OK to just run the
following, or will i need to rebuild the associated index?
alter column ALTER TABLE public.mytable
ALTER COLUMN fts TYPE tsvector ;
The current type is public.tsvector;
Thanks.
