Hi,
I would like to have a simple way to retrieve information for a field name.  
By that I mean have some SQL select that will return all the tables a field 
name exist within a database.  I did not find anything with google but of 
course google depends on the search string.

Thanks in advance,
Johnf

Hi John,

everything you need is stored in these tables:
http://www.postgresql.org/docs/7.4/static/catalog-pg-attribute.html
http://www.postgresql.org/docs/7.4/static/catalog-pg-class.html
http://www.postgresql.org/docs/7.4/static/catalog-pg-namespace.html

You could also do something like:

select nspname, relname, attname
from pg_attribute a
 JOIN pg_class c ON (a.attrelid = c.oid)
 JOIN pg_namespace n ON (n.oid = c.relnamespace)
where a.attname ~ 'yourcolumn'
and c.relname !~ 'pg'
and n.nspname not in ('pg_catalog','information_schema')
order by 1,2,3;

I'd functionalize it.
