No need for apologies, we're not seeking for the one to blame.

What I'd like to emphasize is that some kind of announcement mechanism 
for those of us who code system schema and version dependent stuff is 
desirable, exceeding commit messages. psql issues are discussed 
integratedly on pgsql-hackers; usually, schema changes are tracked 
immediately within the very same cvs commit, making psql a privileged 
tool (to me, it's just another tool). Additional tools require the same 
attention by maintainers, but it's much harder for them.

Multiversion tools are even more challenging, maintainance not made 
easier by the documentation that won't mark version differences 
(something like "this feature was added in ..." would be really nice).

If we had some "admin-announcement@pgsql.org" list anybody who noticed 
some schema relevant change could post there (e.g. usually Dave, Chris 
or me will notice sooner or later) instead of just fixing the stuff 
silently for his own tool only. Postings by committers who think "hey, 
some tool maintainers might want to know this" welcome too.

Andreas
