Ignore ~/.psqlrc when using psql

You can ignore your ~/.psqlrc when running psql commands by using the -X or --no-psqlrc flags.

So when you have all this in your rc file:

/* ~/.psqlrc */
\x auto
\set PROMPT1 '%[%033[1m%]%M %n@%/%R%[%033[0m%]%# '
\set PROMPT2 '[more] %R > '
\pset null '☢'
\setenv PSQL_PAGER pspg
\setenv PAGER pspg

This command becomes quite noisy:

psql -c 'select 1'
Expanded display is used automatically.
Timing is on.
Null display is "☢".
Time: 0.210 ms
(1 row)

Time: 0.297 ms

If you run without the config file:

psql -X -c 'select 1'
(1 row)

on-line manual pages:

    Do not read the start-up file (neither the system-wide psqlrc file nor the
    user's ~/.psqlrc file).
