Bug reference:      4397
Logged by:          Rudolf Leitgeb
Email address:      r(dot)leitgeb(at)x-pin(dot)com
PostgreSQL version: 8.3.3
Operating system:   OSX Leopard
Description:        crash in tab-complete.c
Details: 

When I compiled postgresql for different targets (i386, x86_64, ppc, ppc64)
on my Mac, tab-complete.c gave me a number of warnings, that integers are
converted to pointers. Sure enouugh, psql bombs as soon as I hit the TAB key
...

How to reproduce:

- Compile psql for x86_64. This can be easily done with the following
commands:

CFLAGS="-Os -arch x86_64" LDFLAGS="-arch x86_64" ./configure
--disable-depend  --with-pam  --with-openssl
--prefix=/Users/rleitgeb/pq_x86_64

make

make install

- Then connect to a database with psql and hit tab. gdb will output the
following:

postgres=# 
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000809000
0x00000001001fa1dc in fn_complete ()
(gdb) bt
