Get rid of ESCAPE_PATCH ifdef, as its on by default, and there is no
apparent reason for turning it off...it fixes a bug

Removed #ifdef's for OPENLINK_PATCH.  We enable it by default, and nobody
*has* to enable the functionality, but no reason to retain the "old code"

features(?) are available

Further ports should *really* avoid backend/port and make use of

Thanks D'Arcy.

I hope everyone has sys/socket.h.

If I have introduced any syntax errors with this, I will patch them in
the morning, and Marc will have a good laugh.

cache.  I found if I manually added a line to flush the whole relation
cache, the assert error disappeared.  Looking through the code, I found
that the relation cache is flushed at the end of each query if the
reference count is zero for the relation.  However, printf's showed that
the rd_relcnt(reference count) for the accessed query was not returning
to zero after each query.

It turns out the parser was doing a heap_ropen in parser/analyze.c to
get information about the table's columns, but was not doing a
heap_close.

This was causing the query after the ALTER TABLE ADD to see the old
table structure, and the executor's assert was reporting the problem.

correct way to do this.  Theoretically you could have a NULL
pointer that isn't represented internally as all 0 bits.  This
guarantees that it convert correctly.
