- * oidrand (oid o, int4 X)-
- *	  Takes in an oid and a int4 X, and will return 'true' about 1/X of
- *	  the time.  If X == 0, this will always return true.
- *	  Useful for doing random sampling or subsetting.
- *
- * Example use:
- *	   select * from TEMP where oidrand(TEMP.oid, 10)
- * will return about 1/10 of the tuples in TEMP
- *
- * NOTE: the OID input is not used at all.	It is there just because of
- * an old optimizer bug: a qual expression containing no variables was
- * mistakenly assumed to be a constant.  Pretending to access the row's OID
- * prevented the optimizer from treating the oidrand() result as constant.
