The following documentation comment has been logged on the website:

Description:
Hi,
I could not find description of arrays for 9.6 Postgres:
https://www.postgresql.org/docs/9.6/static/sql-copy.html
Array fields have different format than all other data. They have it's own
header - and i want to know field description.
I added hardcode support of smallint[] into this module:
https://github.com/altaurog/pgcopy
And need full description to create full support of arrays.

I do not think it's explicitly documented anyplace (neither is
the binary format for anything else, really). But you can work
it out easily enough by looking at array_send and array_recv:
