The problem is that postgres.h include palloc.h which contains extern
declaration of MemoryContext global variable. It is not correct for
tools as pg_dump is. Because it does not use palloc. When I enabled
inline functions and start compiling postgres with sunstudio, linking
phase failed on pg_dump because MemoryContext is not allocated. It is
background of problem.
pg_dump.c needs some macros which are defined into catalogs header. But
it should not include postgres.h where is defined "sugar words" for
catalog data. It is the reason why I moved these macros to the separate
header and include this header from all catalog header.
It was discussed there:
