Saluton,
I somehow get the impressions that support for arrays is not a high
priority with PostgreSQL, even though I think it would be very
handy. On the other hand, the system itself uses arrays e.g. for user
groups, so I guess there should be readily available
functions/operators for dealing with that, but I cannot seem to be
able to find them.
Is there a simple way of checking whether e.g. a given int4 is in a
given int4-array?
Is there a way to "thread" a command over an array? By this I mean:
Given an array {1, 2, 3} and a table t like
id | name
--------|--------
1 | joe
2 | fred
3 | mark
, a call to select thread('||', t, {1,2,3}) should produce
'joefredmark'.
Thanks in advance,
Albert.
