Cygwin with the possible exception of mSQL-interface. Since I don't have mSQL installed, I skipped this tool. Except for dealing with a missing getopt.h (oid2name) and HUGE (seg), the bulk of the patch uses the standard PostgreSQL approach to deal with Windows DLL issues. I tested the build aspect of this patch under Cygwin and Linux without any ill affects. Note that I did not actually attempt to test the code for functionality. The procedure to apply the patch is as follows: $ # save the attachment as /tmp/contrib.patch $ # change directory to the top of the PostgreSQL source tree $ patch -p0 </tmp/contrib.patch Jason |

ISBN (books) and ISSN (serials) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This directory contains definitions for a couple of PostgreSQL external types, for a couple of international-standard namespaces: ISBN (books) and ISSN (serials). Rather than just using a char() member of the appropriate length, I wanted my database to include the validity-checking that both these numbering systems were designed to encompass. A little bit of research revealed the formulae for computing the check digits, and I also included some validity constraints on the number of hyphens. The internal representation of these types is intended to be compatible with `char16', in the (perhaps vain) hope that this will make it possible to create indices of these types using char16_ops. These are based on Tom Ivar Helbekkmo's IP address type definition, from which I have copied the entire form of the implementation. Garrett A. Wollman, August 1998
