I don't think so for this case; I got stuck on this for awhile too. It
seems that "oidint4" is an actual data type, so has an "oidint4eq"
comparison function. The parser/planner/optimizer is finding the correct
functions, which are "oideqint4" and "int4eqoid". 

Don't know what "oidint4" actually does or how it's used. Confusing...
