This is a vendor's database and we don't have control over it, nor do we have direct access to the Postgresql table layouts. We are given a spreadsheet to show us what the data types are.

As for the data, sometimes tbl.costcenter can be blank on some records. Surely that wouldn't interfere with the IN operator?

AND (TRIM(tbl.costcenter) IN ('540'))

Can anyone shed some light on this for me?

​It works...

​WITH tbl (id, costcenter) AS ( VALUES (1, '500'), (2, '550') )
SELECT *
FROM tbl
WHERE (trim(tbl.costcenter) IN ('550'));

So the problem resides in something you haven't show us - namely data.
