! Seems like you'd better raise this with the author(s) of the "pg"
! Ruby gem. Perhaps they read this mailing list, but more likely
! they have a specific bug reporting mechanism somewhere.

Tom,
I don't think this has anything to do with "pg". Just checked: I get
garbage and misbehaviour on the "psql" command line tool also:

$ psql -h myhost flowmdev
psql (12.1)
GSSAPI-encrypted connection
Type "help" for help.

flowmdev=> select * from flows;
message type 0x44 arrived from server while idle

flowmdev=> select * from flows;

id | name | ... <here finally starts the data as expected>

To the contrary:

$ PGGSSENCMODE="disable" psql -h myhost flowmdev
psql (12.1)
Type "help" for help.

flowmdev=> select * from flows;
id | name | ... <all working as normal>
