Обсуждение: Where I can find the achieve of the 'generate_series' ?
Hi team,
I want to figure out the principle of the function 'generate_series', but I don't know it contains in which source file.(I download the pgsql 15.3 source code)
Can someone provide some advice?
Thanks in advance!
Yours,
Wen Yi

select proname,prosrc,prosupport from pg_proc where proname ~* 'generate_series';
then grep the prosrc.
