Here are some little changes to the postgreSQL server backend I found beeing convenient for me while I was attempting to get interoparability with a binary only program. The patch attached is tested and works
for 8.0.0beta3.The so called big ones under these DBMS eat the following kind of join without complaining:
select a.val1, b.val2, c.val3 from t1 a left outer join t2 b on (a.id1=b.id2), t1 left outer join t3 c on (a.id1=c.id3);the content of the patch reorders the parse tree to get the same result as this (working recursively for subselects etc.):
select a.val1, b.val2, c.val3 from t1 a left outer join t2 b on (a.id1=b.id2) left outer join t3 c on (a.id1=c.id3); Wolfgang
