It seems that the limit is not on the actual length of the where clause
but on the number of tables which can be referenced by one query (at
least in the where clause).

It appears that I can execute any combination of and's and or's in a
where clause as long as I don't access more than 3 tables.  The minute I
try to access 4 tables, even in a simpler query, Postgres simply returns
an empty table, even if there are tuples which match the query.
