Bug reference: 6117
Logged by: Aleksey Tsalolikhin
Email address: atsaloli.t...@gmail.com
PostgreSQL version: 8.4.8
Operating system: CentOS 5.5 (64-bit)
Description: psql -c does not work as expected. a documentation bug?
a program bug?
Details:
The psql man page says, in the section for the -c option:
If the command string contains multiple SQL
commands, they are processed in a single
transaction
However when I run a command string with multiple
SQL commands, apparently only the last one is
processed.
For example:
# psql -U postgres -c "select now(); select now(); select version();"
version
----------------------------------------------------------------------------
--------------------------------------
PostgreSQL 8.4.8 on x86_64-redhat-linux-gnu, compiled by GCC gcc (GCC)
4.1.2 20080704 (Red Hat 4.1.2-48), 64-bit
(1 row)
#
Yet this works fine:
# echo "select now(); select now(); select version();"|psql -f- -U postgres
now
-------------------------------
2011-07-13 13:51:01.594725-07
(1 row)
now
-------------------------------
2011-07-13 13:51:01.597903-07
(1 row)
version
----------------------------------------------------------------------------
--------------------------------------
PostgreSQL 8.4.8 on x86_64-redhat-linux-gnu, compiled by GCC gcc (GCC)
4.1.2 20080704 (Red Hat 4.1.2-48), 64-bit
(1 row)
#
This is what I expect to see.
Could you please fix psql or make the documentation for the -c option more
clear?
Thanks very much and thanks for a great product!
Yours truly,
Aleksey
