You hit the upper limit of internal memory allocation limit in
PostgreSQL. IMO, there's no way to avoid the error except you use
client encoding identical to backend.
Hackers:
The particular limit seem to be set considering TOAST(from
include/utils/memutils.h):
* XXX This is deliberately chosen to correspond to the limiting size
* of varlena objects under TOAST. See VARSIZE_4B() and related macros
* in postgres.h. Many datatypes assume that any allocatable size can
* be represented in a varlena header.
IMO the SQL string size limit is totally different from
TOAST. Shouldn't we have different limit for SQL string?
(MAX_CONVERSION_GROWTH is different story, of course)
