In 02b8048ba I (tgl) got rid of the need for most tab-completion queries
to return pre-quoted identifiers. But I over-hastily removed the
quote_ident call from Query_for_list_of_available_extension_versions*
too; those still need it, because what is returned isn't an identifier
at all and will (almost?) always need quoting.
Arguably we should use quote_literal here instead. But quote_ident
works too and people may be used to that behavior, so stick with it.
In passing, fix inconsistent omission of schema-qualification in
Query_for_list_of_encodings. That's not a security issue per our
current guidelines, but it ought to be like the rest.
