Good idea, new code applied:
# Supply a numeric version string for use by 3rd party add-ons# awk -F is a regex on some platforms, and not on others,
somake "." a tabPG_VERSION_NUM="`echo "$PACKAGE_VERSION" | sed 's/[A-Za-z].*$//' |tr '.' ' ' |$AWK '{printf
\"%d%02d%02d\",$1, $2, (NF >= 3) ? $3 : 0}'`"AC_DEFINE_UNQUOTED(PG_VERSION_NUM, $PG_VERSION_NUM, [PostgreSQL version as
anumber])
