in UPDATE. We also now issue a NOTICE if a query has _any_ implicit range table entries -- in the past, we would only warn about implicit RTEs in SELECTs with at least one explicit RTE. As a result of the warning change, 25 of the regression tests had to be updated. I also took the opportunity to remove some bogus whitespace differences between some of the float4 and float8 variants. I believe I have correctly updated all the platform-specific variants, but let me know if that's not the case. Original patch for DELETE ... USING from Euler Taveira de Oliveira, reworked by Neil Conway.
