Using COPY via pg_background extension

Hello everyone,

I couldn't find anything on this topic in the mailing lists or in the documentation for the ‘pg_background’ extension.

https://github.com/vibhorkum/pg_background?tab=readme-ov-file#known-limitations

Perhaps I overlooked something.

My question is: Is it possible to use the COPY protocol in combination with pg_background?

More specifically, is it possible to load data from a file into a table via background worker process?  

COPY country FROM ‘/usr1/proj/bray/sql/country_data’;

Would the following call or something similar be possible and achieve the desired result??

pg_background_launch_v2(‘COPY country FROM ’/usr1/proj/bray/sql/country_data');

Kind regards,

Oleg
