> Source functions should also support the parameterized native-query extension property to easily add calls that use non-standard or mapped function syntax.  
> For an operator like pg bit shift left:
> {code}
> create foreign function bsl (arg1 integer, arg2 integer) returns integer OPTIONS ("teiid_rel:native-query" '$1 << $2')
> {code}
> For an oracle sequence:
> {code}
> create foreign function seq_nextval () returns integer OPTIONS ("teiid_rel:native-query" 'seq.nextval')
> {code}
