hi.

we need to escape the semicolon within the single quotes or double quotes.
I think my patch in [1] is correct.

we can have "ERROR: role "z" already exists
but
error message like
pg_restore: error: could not execute query: "ERROR: unterminated
quoted string at or near "';
should not be accepted in execute_global_sql_commands, ReadOneStatement, PQexec

attached is the all the corner test case i come up with against
ReadOneStatement.
your v13 will generate errors like "ERROR: unterminated quoted string
at or near ..."',
which is not good, i think.
