Attached is a trivial improvement to ecpg's pgtypeslib: (1) `pstr' must
be non-NULL in this function, so no need to check for it (2) we should
check the return value of pgtypes_strdup(). Patch from Eric Astor at
EDB, with slight cleanup by myself, to fix a Coverity report.
Barring any objections I'll apply this to HEAD later today.
