There's an example in the docs that fetches multiple rows into an array. 
See https://www.postgresql.org/docs/18/ecpg-descriptors.html:

thiscase assumes that the variable is an array. E.g.:

P.S. Please post usage questions like this to pgsql-general in the 
future, the pgsql-bugs list is for reporting bugs.
