Hi,

I wonder if there is some kind of support for PostgreSQL's arrays in
psycopg? The fetch routines return the literal array syntax of
PostgreSQL. I'd want the fetch routines to return a list for
PostgreSQL's arrays, with the common types (text, int, timestamp)
handled like they are everywhere else in psycopg.


if someone provides me with a foolprof way to extract type information
from arrays i'll implement it. :/


It seems to me that for TEXT[] PQftype() returns 1009, and 1009 is hard
coded to be array of text, as I understand it (see also pg_type.typelem,
which is 25, the oid for text). Similarly for the other types. Wouldn't
that information be enough?

Thanks
