Fix case sensitivity for PostgreSQL and Oracle identifier quoting

PostgreSQL folds unquoted identifiers to lowercase, so double-quoted
identifiers must also be lowercase to match. Oracle folds unquoted
identifiers to uppercase, so double-quoted identifiers must be
uppercase.

Without this fix, quoting mixed-case table/column names causes
"relation not found" errors because the quoted name doesn't match
the case stored in the database.
