      - Put operator "->" back into parser. Note that :foo->bar means the

From: Michael Meskes <meskes@topsystem.de>

Here's my next patch. this one should fix some more bugs. ecpg now fully
understands the whenever statement.

From: Michael Meskes <meskes@topsystem.de>

Here's the ecpg patch for the local variables bug I reported earlier:

Cleanups for ecpg, as well as a missing patch so that its configured in

Well this is not really a patch. But I mananged to get Linus' old Postgres95
precompiler to compile and work with PostgreSQL. The next step would be to
collect bug/missing feature reports and to put it into the distribution so
that it is made with the standard make procedure.

Warning! So far it is not tested much and it does not install correctly. But
I was able to create a small binary with it.
