I applied v4 and got an assertion failure with the following script.
pg_stat_statements is in shared_preload_libraries.

=# CREATE EXTENSION pg_stat_statements;
=# CREATE TABLE t (a int);
=# SELECT 1\; PREPARE p AS SELECT a FROM t WHERE a > 1\; SELECT 2;
=# ALTER TABLE t ADD COLUMN b int;
=# EXECUTE p;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
TRAP: failed Assert("query_len <= strlen(query)"), File:
"queryjumblefuncs.c", Line: 102
