Outliers doesn't handle timing information

[mble]

When we introduced handling of PG13s new field, we make an assertion about the array of results received:

heroku-pg-extras/lib/util.js

Line 34 in 6dded5b

if (newTotalExecTimeField.length != 6) {

This is non-deterministic because the output depends on what you've got in .psqlrc. For example, I have \timing in mine which extends the array to having 7 elements.

We should ignore .psqlrc for pg:* commands that are only invoking psql in order to get a connection to the database.
