pgbench: increase the maximum number of variables/arguments
pgbench's arbitrary limit of 10 arguments for SQL statements or
metacommands is far too low. Increase it to 256.
This results in a very modest increase in memory usage, not enough to
worry about.
The maximum includes the SQL statement or metacommand. This is reflected
in the comments and revised TAP tests.
