Hi Augustin,

PostgreSQL has a couple of possibilities in this regard.
For example, http://stackoverflow.com/questions/1152260/postgres-sql-to-list-table-foreign-keys has a couple of very clear queries.

Additionally, it would be very useful if you could further clarify the problem you are trying to solve.

Hi everyone:

I want to know if exists a postgres function or some easy way to know if a PK in a table is already referenced in another table/tables.

e.g.
I want to delete a row but first I've got to change or delete in the table/tables where is referenced, and I have many table where could be referenced.
