Hello!
I want to update a old postgresdatabase. In the time of databasecreation
the postgres had no "references" construct. So the integrity is
maintained by the C-Driver.
Now I want to build in the integrity. But i have to maintain
compatibiliy to old databases in the code itself.
So my question:
HOW can I determine if the database has referential integrity used or
not? Are there in the database any "references" in use or not?
Maybe it is descripted in any systemtable(pg_xyz)?
Thanks in advance
David
