BTW, have you read the (extensive) prior discussion of this topic? For
example,

http://archives.postgresql.org/pgsql-patches/2004-07/msg00229.php

There have been *at least* two previous implementations of the patch
posted, so it might be worth taking a look at those other versions as
well.

Can you post this as a separate patch, please? It is unrelated, and the
bulk of these changes make it difficult to review the "-t" option work.

+ char *pg_strdup(const char *s);

By convention, global function declarations use the "extern" keyword, so
you want:

extern void *pg_malloc(size_t sz);

etc.
