I'm using postgresql 9.1. I have the column name of a table. Is it possible to find the table(s) that has/have this column? How? Thanks in advance.
you can query system catalogs:
from pg_class as c
inner join pg_attribute as a on a.attrelid = c.oid
where a.attname = <column name> and c.relkind = 'r'
