Nothing checks the command result, so the test file passes even if each of
these createdb calls fails. Other run_log() calls in this file have the same
problem. This particular one should be command_ok() or similar.
--host and --port are redundant in a PostgreSQL::Test::Cluster::run_log call,
because that call puts equivalent configuration in the environment. Other
calls in the file have the same redundant operands. (No other test file has
redundant --host or --port.)

src/test/recovery/t/027_stream_regress.pl and the makefiles treat
EXTRA_REGRESS_OPTS as a shell fragment. To be compatible, use the
src/test/recovery/t/027_stream_regress.pl approach. Affected usage patetrns
are not very important, but since the tree has code for it, you may as well
borrow that code. These examples witness the difference:
EXTRA_REGRESS_OPTS='--nosuc" h"' MAKEFLAGS= make -C src/bin/pg_upgrade check
PROVE_TESTS=t/002_pg_upgrade.pl
# log has:
/home/nm/src/pg/postgresql/src/bin/pg_upgrade/../../../src/test/regress/pg_regress:
unrecognized option '--nosuc"'
EXTRA_REGRESS_OPTS='--nosuc" h"' MAKEFLAGS= make -C src/test/recovery check
PROVE_TESTS=t/027_stream_regress.pl
# log has:
/home/nm/src/pg/postgresql/src/test/recovery/../../../src/test/regress/pg_regress:
unrecognized option '--nosuc h'

This rewrite dropped the exercise of backslashes adjacent to double quotes.
