pgsql: Fix test_decoding regression test outputs.

Fix test_decoding regression test outputs.

Commit 6f37c08057685ee3c6c63222dba0dac012760dde removed whitespace
from the SQL file but not the expected-output file, and commit
7e8db2dc420099df3fa73987cf2d2d6d1a609d86 changed the error message
without updating the expected outputs.
