Yeah, I agree. Looks like a simple change in dbconnect():
/*
* Use old password if no new one given (if you didn't have an old
* one, fine)
*/
if (!pwparam && oldconn)
pwparam = PQpass(oldconn);
to
/*
* Use old password (if any) if no new one given and we are
* reconnecting as same user
*/
if (!pwparam && oldconn && PQuser(oldconn) && userparam &&
strcmp(PQuser(oldconn), userparam) == 0)
pwparam = PQpass(oldconn);

current_timestamp, current_date for ODBC compatibility.
Add more functions to odbc.sql catalog extension, use new CREATE OR
REPLACE FUNCTION.
Document iODBC/unixODBC build options.
That patch broke the ability to read data from binary cursors.

NOTICE added about error location (same method already used by plpgsql
executor). Add checking of pg_proc row xmin/cmin to ensure that
plpgsql functions will be recompiled after they've been modified by

rather than having its own somewhat half-baked notion of what a type
declaration looks like. This is necessary now to ensure that plpgsql
will think a 'timestamp' variable has the same semantics as 'timestamp'
does in the main SQL grammar; and it should avoid divergences in future.
for nested typecasts. It now produces a column header of 'timestamptz'
for 'SELECT CURRENT_TIMESTAMP', rather than 'text' as it was doing for
awhile there.
lookup info in the relcache for index access method support functions.
This makes a huge difference for dynamically loaded support functions,
and should save a few cycles even for built-in ones. Also tweak dfmgr.c
so that load_external_function is called only once, not twice, when
doing fmgr_info for a dynamically loaded function. All per performance

following work in psql:
\d foo \d bar
\d foo; \d bar
\d foo \d bar;;
\d foo; <space>
This one also uses "true and false" and strips semicolons
for the following backslash commands: \C \c \d \e \i \o \s \z

readability. Bizarre '(long *) TRUE' return convention is gone,
in favor of just raising an error internally in dynahash.c when
we detect hashtable corruption. HashTableWalk is gone, in favor
of using hash_seq_search directly, since it had no hope of working
with non-LONGALIGNable datatypes. Simplify some other code that was
made undesirably grotty by promixity to HashTableWalk.
type coercion after failing to find an exact match in pg_proc, but before
considering interpretations that involve a function call with one or
more argument type coercions. This avoids surprises wherein what looks
like a type coercion is interpreted as coercing to some third type and
then to the destination type, as in Dave Blasby's bug report of 3-Oct-01.
See subsequent discussion in pghackers.

One problem, after this patch errors will generate multiline ERROR
messages. Is it acceptable or do I need split it and generate multiple
singleline messages?
