I was just reading the PostgreSQL documentation about Information Schemas. Some of the tables have fields which are described as
"Applies to a feature not available in PostgreSQL"

What does that mean?

The information schema is a part of the SQL standard that allows access to information about the structure of the database schema. PostgreSQL strives to implement the SQL standard, but there are some features of the SQL standard that PostgreSQL has not yet implemented or has decided not to. You can check SQL conformance in the documentation.

Ah, thanks. I didn't realize this was part of the SQL standard.
