Hello! We have stumbled upon a strange issue after upgrading from PostGIS 3.3.0 to 3.6.0.
A simple query like  select * from foo.bar where ST_IsValid(geometry)  executed in DBeaver returns the following error:
SQL Error [08006]: An I/O error occurred while sending to the backend  if the size of this table is like 6 Mb or more. While executing DBeaver shows something like connection attempts and finally invalidates/reconnects with this error message.

Looking forward,
