o What is pgbench?

(10,000,000) tuples in the accounts table.

default is 1.

-U login

Specify db user's login name if it is different from

the Unix login name.

-P password

Specify the db password. CAUTION: using this option

might be a security hole since ps command will

show the password. Use this for TESTING PURPOSE ONLY.

-n

No vacuuming and cleaning the history table prior the

test is performed.

-S

Perform select only transactions instead of TPC-B.

-C

Establish connection for each transaction, rather than

doing it just once at begining of pgbench in the normal

mode. This is usefull to measure the connection overhead.

-d

debug option.

o History

2001/09/09

* Add -U, -P, -C options

2000/1/15 pgbench-1.2 contributed to PostgreSQL

* Add -v option
