/*-------------------------------------------------------------------------
*
* genbki.h
* Required include file for all POSTGRES catalog header files
*
* genbki.h defines CATALOG(), BKI_BOOTSTRAP and related macros
* so that the catalog header files can be read by the C compiler.
* (These same words are recognized by genbki.pl to build the BKI
* bootstrap file from these header files.)
