I was trying to compile these patches on latest
head(f90d23d0c51895e0d7db7910538e85d3d38691f0) for some testing but I
was not able to compile it.

make[3]: *** [postgres.bki] Error 1
make[3]: Leaving directory
`/home/dilip/work/pg_codes/pbms_final/postgresql/src/backend/catalog'
make[2]: *** [submake-schemapg] Error 2
make[2]: Leaving directory
`/home/dilip/work/pg_codes/pbms_final/postgresql/src/backend'
make[1]: *** [all-backend-recurse] Error 2
make[1]: Leaving directory `/home/dilip/work/pg_codes/pbms_final/postgresql/src'
make: *** [all-src-recurse] Error 2

I tried doing maintainer-clean, deleting postgres.bki but still the same error.
