Numeric literals too large to fit in an int are interpreted as floats.
You can work around the issue by explicitly coercing the literal to
numeric, or by single-quoting it (so that its type is not determined
until after agency_uid is known to be numeric), or by updating to PG
7.2 which uses a slightly different set of type-resolution rules.
