While we MySQL developers are willing to validate our queries against an SQL validator but the problems are usually not on this level. Some examples are: text fields without defaults work on MySQL (even they can't have a default if i remember correctly) but not on pgsql so we need to supply a value. DDL have different syntax -- schema solved a lot but not all.

So let me reiterate my proposal: If a patch works on MySQL and has a good chance of working on postgresql -- because the queries validate or the specific features exist on postgresql but there can be syntax differences etc -- then please commit it. This is not, again NOT going down the "one database route" -- we will validate our queries, will still look into the postgresql manual as we did before etc to ensure things are OK -- just please let the postgresql folks test when they have time / resource without holding up the other whatever significant percent of core developers.
