Is there some way to check if postgresql is working well with Sid?

There are 3 main symptons:

1. I can't locate the postgres executable so I can run different servers.

2. psql generates this error:

/usr/lib/postgresql/9.4/bin/psql: symbol lookup error: /usr/lib/postgresql/9.4/bin/psql: undefined symbol: PQconninfo


3. This is the content of the postgresql.log

Hello vonh,

postgresql is not a typical desktop application. We do neither deliver nor support it officially
and I will move this topic to another category eventually.

For configuration options please refer to https://wiki.debian.org/PostgreSql

I successfully installed the postgresql metapackage, which always depends on the currently supported PostgreSQL database server version and its client. The currently supported version is postgresql-9.4.

root@sidbox:~# dpkg -L postgresql-9.4 | grep bin
[...]
/usr/lib/postgresql/9.4/bin/postgres

root@sidbox:~# systemctl status postgresql

It turns out I had to use apt-get install postgresql-client-9.4 rather than apt-get install postgresql-client as for some reason that command was installing postgresql-client:i386.
