It will create text files, that is actually the default:

https://www.postgresql.org/docs/10/static/app-pgdump.html


-F format
--format=format

     Selects the format of the output. format can be one of the following:

     p
     plain

         Output a plain-text SQL script file (the default).

You are correct Git will catch the changes in the plain text files.

What is nice about Sqitch and similar tools is they offer additional 
functionality, such as deploying to different servers(production, dev, 
testing, etc), declaring dependencies between changes, rolling back 
individual changes, etc. To get a sense of what is possible take a look 
here:

I have found it very useful. It comes down to individual preference.
