fix(postgres): treat FULLTEXT and SPATIAL as unreserved identifiers

FULLTEXT and SPATIAL are MySQL-specific table constraint keywords. When
parse_optional_table_constraint encountered them in a PostgreSQL context
it would consume the token, fall through to the _ arm, and call
prev_token() to restore it — but the consume-then-backtrack round-trip
left room for a subtle parser-state bug that caused the next call to
parse_data_type to see 'fulltext' instead of the actual column type.

Fix: add an explicit peek-based guard at the top of
parse_optional_table_constraint so that for dialects other than MySQL /
Generic the FULLTEXT / SPATIAL tokens are never consumed at all. The
caller (parse_columns) then correctly falls through to parse_column_def
and treats the word as an ordinary column identifier.

Also add a parser unit test covering a tsvector column literally named
'fulltext' (as in the pagila DVD-rental schema) and a GiST index that
references the same column by name.

Bump version to 0.60.13.
