This patch fixes the delete manual page in 2.0:

Subject: [PG95-DEV] postgres.h patch
This removes the parameters from the func_ptr prototype in postgres.h in
2.0.

Subject: [PG95-DEV] Makefile.global patch
Can we apply the following patch to make EUROPEAN_DATES consistent with
other parameters?
way one creates a database system. Parts that were in "make install"
are not either in "make all" or initdb. Nothing goes in the PGDATA
directory besides user data. Creating multiple database systems is
easier.
In addition to applying the patch, it is necessary to move the file
libpq/pg_hba to backend/libpq/pg_hba.sample.

- Added the header access/heapam.h.
- Changed all instances of "length" to "data_length" to quiet
the compiler.
- initialized a few variables. The compiler couldn't see that
the code guaranteed that these would be initialized before
being dereferenced. If anyone wants to check my work follow
the usage of these variables and make sure that this true
and wasn't actually a bug in the original code.
- added a missing break statement to a default case. This
was a benign error but bad style.
- layed out heap_sysattrlen differently. I think this way
makes the structure of the code crystal clear. There should
be no actual difference in the actual behaviour of the code.

NOTE: Makefile.custom is commented out, since it isn't there by default.
If you read the section telling you about it to know to create it,
you can uncomment it while you are there ...
current state of development...namely, we are on 2.0
NOTE:
BTW, the is also a check in postmaster which won't let you use an older
version of the database by checking the version number. The version number
of a database is in data/PG_VERSION (a plain ASCII file).

attributes as tcl arrays. The previous code had problems with some chars
used as delimiter by Tcl. The new code should be more robust.

Async notifies received while a backend is in the middle of a begin/end
transaction block are lost by libpq when the final end command is issued.
The bug is in the routine PQexec of libpq. The routine throws away any
message from the backend when a message of type 'C' is received. This
type of message is sent when the result of a portal query command with
no tuples is returned. Unfortunately this is the case of the end command.
As all async notification are sent only when the transaction is finished,
if they are received in the middle of a transaction they are lost in the
libpq library. I added some tracing code to PQexec and this is the output:
