2024-12-04Use <stdint.h> and <inttypes.h> for c.h integers.Thomas Munro
Redefine our exact width types with standard C99 types and macros, including int64_t, INT64_MAX, INT64_C(), PRId64 etc. We were already using <stdint.h> types in a few places. One complication is that Windows' <inttypes.h> uses format strings like "%I64d", "%I32", "%I" for PRI*64, PRI*32, PTR*PTR, instead of mapping to other standardized format strings like "%lld" etc as seen on other known systems. Teach our snprintf.c to understand them. This removes a lot of configure clutter, and should also allow 64-bit numbers and other standard types to be used in localized messages without casting.

2018-09-06Refactor dlopen() supportPeter Eisentraut
Nowadays, all platforms except Windows and older HP-UX have standard dlopen() support. So having a separate implementation per platform under src/backend/port/dynloader/ is a bit excessive. Instead, treat dlopen() like other library functions that happen to be missing sometimes and put a replacement implementation under src/port/.

2012-10-07Autoconfiscate selection of 64-bit int type for 64-bit large object API.Tom Lane
Get rid of the fundamentally indefensible assumption that "long long int" exists and is exactly 64 bits wide on every platform Postgres runs on. Instead let the configure script select the type to use for "pg_int64". This is a bit of a pain in the rear since we do not want to pollute client namespace with all the random symbols that pg_config.h defines; instead we have to create a separate generated header file, "pg_config_ext.h". But now that the infrastructure is there, we might have the ability to add some other stuff that's long been wanting in this area.
