yii: Updated postgres 12 query for findColumns function returns wrong sequence name in the result

Postgres 12 updated the findColumns function and the following query when run for a database table whose name and sequence name were updated after it was created returns old sequence name when this query gets executed.

SELECT a.attname, LOWER(format_type(a.atttypid, a.atttypmod)) AS type, d.adsrc AS column_def_value, a.attnotnull, a.atthasdef, pg_catalog.col_description(a.attrelid, a.attnum) AS comment FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attnum > 0 AND NOT a.attisdropped AND a.attrelid = (SELECT oid FROM pg_catalog.pg_class WHERE relname=:table AND relnamespace = (SELECT oid FROM pg_catalog.pg_namespace WHERE nspname = :schema)) ORDER BY a.attnum

Old query that gets generated by findColumns function before postgres12 upgrade code was added gives the right sequence name for the same table

SELECT a.attname, LOWER(format_type(a.atttypid, a.atttypmod)) AS type, CAST(pg_get_expr(d.adbin, d.adrelid) AS varchar) AS adsrc, a.attnotnull, a.atthasdef, pg_catalog.col_description(a.attrelid, a.attnum) AS comment FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attnum > 0 AND NOT a.attisdropped AND a.attrelid = (SELECT oid FROM pg_catalog.pg_class WHERE relname=:table AND relnamespace = (SELECT oid FROM pg_catalog.pg_namespace WHERE nspname = :schema)) ORDER BY a.attnum
