Modify information in resulting error message to indicate both agg name
 and data type.

31d825ba07 While investigating a user's complaint, I have found some memory 
destructions in 6.4 source using purify.

(1) parser/gram.y:fmtId()

It writes n+3 bytes into n+1 byte-long memory area if mixed case or
non-ascii identifiers given.

(2) catalog/index.c:

ATTRIBUTE_TUPLE_SIZE bytes are allocated but
sizeof(FormData_pg_attribute) bytes are written. Note that
ATTRIBUTE_TUPLE_SIZE is smaller than
sizeof(FormData_pg_attribute). (for example, on solaris 2.6,

cd3a8e232c change configure so that if postgresql isn't being installed as root, 
do not configure in the perl5 interface.

the perl5 interface needs to be installed under /usr/local/lib/perl5/*, which
is generally owned by root.  This allows a non-root build/install with the
only root requirement being the make/install of hte perl5 stuff...

9b21a18cee the following little patch adds array references to query 
parameters. With it applied a function like

    CREATE FUNCTION getname(oid8, int4) RETURNS name AS
        'SELECT typname FROM pg_type WHERE oid = $1[$2]'
        LANGUAGE 'sql';

    is possible. Mainly I need this to enable array references in
    expressions for PL/pgSQL. Complete regression test ran O.K.

20693de474 Support specifying PRIMARY KEY for the SERIAL type. 
Change DEFAULT NULL to send back a NULL pointer
 rather than a string "NULL". This seems to work, where sending
 the string led to type conversion problems (and probably the wrong
 thing anyway).

7c30ac961f Support specifying PRIMARY KEY for the SERIAL type. 
Check for a constraint if is_sequence is set and omit making
 a UNIQUE index if so, since the primary key will cover that for us.
