+       - Fixed variable detection in libecpg.
+
+ Mon Feb 22 19:47:45 CET 1999
+
+       - Added 'at <db_connection>' option to all commands it is apllicable
+         to. Due to changing the API of some libecpg functions this
+         requires me to increase the major version number.
+       - Synced pgc.l with scan.l.
+       - Added support for unions.
+       - Set library version to 3.0.0
+       - Set ecpg version to 3.0.0

See Changes file...

And the next update. Now you can use only parts of a struct like this:

exec sql select a into :struct.string from foo;

Michael Meskes <meskes@topsystem.de>

handles all transaction commands and the exec sql include command.

No more shift/reduce conflicts. Also all other bugs I know about are fixed.

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.
