Hi,
I am now studying PostgreSQL.
in your web site:
Developer's Frequently Asked Questions (FAQ) for PostgreSQL
Technical Questions
2.1) How do I efficiently access information in tables from the backend code?
Since heap_open function needs the oid of the relation, how can I get those parameters for heap_open?
Suppose that at the beginning, I only know the name of the relation, which functions I need to call?
Best regards.
