From a brief and similar session (below), perhaps the best solution is to
simply insert a space between the '=' and the '-'??

Subject: [GENERAL] doesn't recognize "!=-" (not equal to a negative value)
Version postgres 7.4.7:
Following sql
UPDATE tablename SET value = 0.0 where value!=-9.4;
results in the error message
ERROR: operator does not exist: smallint !=- integer
HINT: No operator matches the given name and argument type(s). You may
need to add explicit type casts.
Seems that postgres has a problem parsing a "not equal negative value".
Anybody know if this is fixed in later versions?
