PostgreSQL psql terminal command

Question

I'm trying to get psql to format nicely and am following the docs here. Right now, whenever I do a query on tables with lots of columns, no matter how big I make my screen each line overflows into the next line and producing a whole screen of unreadable junk.

The docs (link is above) say there's a way to align columns nicely for more readable output.

Normally, to start psql, I just type:

psql

and hit Enter. Now I'm trying:

psql \pset format aligned

And getting an error:

could not change directory to "/root"
psql: warning: extra command-line argument "aligned" ingored
psql: FATAL: Indent authentication failed for user "format"

Any ideas as to how I could get these command-line args to work for me?

Solution 1

These are not command line args. Run psql. Manage to log into database (so pass the hostname, port, user and database if needed). And then write it in the psql program.

Example (below are two commands, write the first one, press enter, wait for psql to login, write the second):

psql -h host -p 5900 -U username database
\pset format aligned

Solution 2

Use \x Example from postgres manual:

    postgres=# \x
    postgres=# SELECT * FROM pg_stat_statements ORDER BY total_time DESC LIMIT 3;
    -[ RECORD 1 ]------------------------------------------------------------
    userid     | 10
    dbid       | 63781
    query      | UPDATE branches SET bbalance = bbalance + $1 WHERE bid = $2;
    calls      | 3000
    total_time | 20.716706
    rows       | 3000
    -[ RECORD 2 ]------------------------------------------------------------
    userid     | 10
    dbid       | 63781
    query      | UPDATE tellers SET tbalance = tbalance + $1 WHERE tid = $2;
    calls      | 3000
    total_time | 17.1107649999999
    rows       | 3000
    -[ RECORD 3 ]------------------------------------------------------------
    userid     | 10
    dbid       | 63781
    query      | UPDATE accounts SET abalance = abalance + $1 WHERE aid = $2;
    calls      | 3000
    total_time | 0.645601
    rows       | 3000

Solution 3

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

For my installation of PostgreSQL 9.6.10, I have to use psql -h host -p port -d database -U user -W, with the settings being case sensitive.
