I'm posting this hoping that I will save some time to someone else.
Here is the query I came up with:
SELECT DISTINCT ordinal_position, column_name, data_type,
character_maximum_length, character_octet_length, numeric_precision,
numeric_precision_radix, numeric_scale, is_nullable, column_default,
CASE WHEN column_name IN (SELECT ccu.column_name FROM
information_schema.constraint_column_usage ccu,
information_schema.table_constraints tc WHERE ccu.constraint_name =
tc.constraint_name AND tc.constraint_type = 'PRIMARY KEY' AND
ccu.table_name = $2) THEN 'YES' ELSE 'NO' END AS is_pk FROM
information_schema.columns col, information_schema.table_constraints
tc WHERE tc.table_schema = col.table_schema AND tc.table_name =
col.table_name AND col.table_schema = $1 AND col.table_name = $2 ORDER
BY ordinal_position;
Is there a better way to do that? I don't mind using Postgres-only solution.
Thank you.
BTW, is there a difference between query a real tables or query a view?
