Hi,

I have an array and I want to import the data rowwise.

Would it make sense to use a function which calls a prepared statement in a loop to import the data performant?

Or can I somehow use the COPY FROM command?

Re: performant import of an array

Hello

import data to auxiliary table, and then use a ARRAY(subselect) or
array_agg function to transformation from table to array.
