pg_type

I added a field to pg_type, updated all the bootstrap catalog entries,
changed Natts_pg_type, and (I think) fixed the two places in pg_type.c
that construct pg_type entries. However, initdb fails at the sysviews
creation stage - the core dump shows it failing as shown below. Anyone
have a quick idea what I might have missed / done wrong? At this stage
the new field is not actually used anywhere, so it can't be a problem
with that.

thanks
