BUG #5899: Memory corruption when running psql

The following bug has been logged online:

Bug reference: 5899
Logged by: Ross Barrett
Email address: ross_barrett(at)rapid7(dot)com
PostgreSQL version: 9.0.3
Operating system: Ubuntu 9.10
Description: Memory corruption when running psql
Details:

Attempting to run psql complains that termcap db is not present (bug 5807).
Applying the work around of placing an /etc/termcap file from a Red Hat
system allowed psql to run 1x. Subsequent runs always yield a memory
error:

psql (9.0.3)
Type "help" for help.
