> The workaround is to do it like this instead:
Strange, I tried to do like this, but the first thing came into my mind was array_agg() not array():
ERROR: operator does not exist: tid = tid[]
delete from log
where ctid = any(
select array_agg(ctid) from (
select ctid from log
where timestamp < now() at time zone 'pst' - interval '2 month'
limit 10
) v);
This query complained like this:
LINE 2: where ctid = any(
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
Which is strange because both array(select ...) and select array_agg() ... return the same datatype ctid[].
> But of course that's still an ugly hack.
Come on... Due to declarative nature of SQL developers sometimes need to write much dirtier and uglier hacks.
This one is just a fluffy hacky.
