More specifically, I have only lightly read this thread - and while I
think the functionality is useful, I have not thought about it any real
depth. I was thinking more along the lines that if I needed
functionality like this, where & how might I look for it.
I was remembering my problems looking up syntax in COBOL after coming
from FORTRAN (& other languages) - some concepts had different names and
the philosophy was significantly different in places. The relevance
here, is that peoples' background in other DBMS & knowledge of SQL
standards affect what they expect, as well as preventing unnecessary
conflicts between PostgreSQL & SQL standards (as far as is practicable &
sensible).
