Please find attached v12 of the patch, which implements that idea.
And a new pg_execute_from_file patch version too: the function now has a
second (documented) variant accepting a VARIADIC text[] argument where
to put pairs of name and value for the placeholders in the script.
I guess it would be cleaner with hstore in core, but we're not there
yet, so meanwhile it's a variable length array.
The CREATE EXTENSION ... WITH SCHEMA ... command will then use the
variadic form of pg_execute_from_file() with a single variable in there,
the proposed @extschema@. When the option is not used, the placeholder
is still set, hard-coded to 'public'.
Contrib scripts have been all changed this way:
- SET search_path = public;
+ SET search_path = @extschema@;
