Hi Guys,

how use git to catch delta between database versions?

Use sqitch?:

https://sqitch.org/

As version i will do schemas.
So we have version one, finishing it, and this version should be put in
GIT.
And created schema for the version.

Which formats i should use?

pg_dump creates only binary files? (i should use text file here).

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).

Best,
Jacek

Hi Adrian,

thank you .

why i should use sqitch or any other software to catch the delta?

When i will export plan-text SQL , git should catch delta automatically?
Can you please explain it?

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.

Jacek
