Hi all, Apologies in advance if this isn't the right place to be posting this.
I've started work on a plugin in C (https://github.com/tanglebones/pg_tuid) for generating generally monotonically ascending UUIDs (aka TUIDs), and after googling around I couldn't find any guidence on a few things. (It's hard to google for anything in the postgres C api as most results coming back are for using postgres itself, not developing plugins for postgres.) I'm looking for the idiomatic (and portable) way of: 1) getting microseconds (or nanoseconds) from UTC epoch in a plugin 2) getting an exclusive lock for a user plugin to serialize access to its shared state (I'm assuming that plugins must be reentrant) 3) creating a configuration variable for a plugin and accessing its values in the plugin. (e.g. `set plugin.configuration_variable=1` or somesuch) Thanks, -- Clifford Hammerschmidt, P.Eng.
