git head crash/regression failures

From

I am seeing psql crash and massive regression test failures in git head.
The psql crash happens if .psqlrc contains:

    \set COMP_KEYWORD_CASE upper

and the crash backtrace is:

    Program received signal SIGSEGV, Segmentation fault.

The regression test seem to be crashing from \d.  For example, in
src/test/regress/results/tablespace.out, once this line appears:

    \d testschema.test_index1

the file ends, while the expected file has many more lines.

Did you try "make maintainer-clean"?

Wow, that fixed it.  I thought my work flow didn't require that, but
obviously it does.  Thanks so much.
