Can't compare functions in Postgres 11

[ErunamoJAZZ]

Hi

I was testing this with a Postgres 11 and I got this error:

loading functions error { error: no existe la columna p.proisagg
    at Connection.parseE (/usr/lib/node_modules/pg-compare/node_modules/pg/lib/connection.js:555:11)

This error make reference to

pg-compare/lib/Schema.js

Line 440 in 2642785

'AND NOT p.proisagg ' +

Googling it, I found now postgres use a column named prokind instead, like you can see in jOOQ/jOOQ#7785
