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-limitati
ons
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');
https://www.postgresql.org/docs/current/sql-copy.html
Kind regards,
Oleg

What happens when you try?
Though be aware that COPY needs server user access to the file.
If there is an error I would suggest reporting it here:

Would "psql run from crontab" serve your purpose just as well?
