pgAdmin reverse engineers the SQL based on the available catalog and schema information. I don't think PostgreSQL saves the exact formatting when creating objects (except function/procedure body).
Yes, Postgres doesn't store the original form of DDL query.
I have a syntax format for SQL that I prefer, so when I craft new Views or what-not I write them out a certain way.
When I save that SQL into a View, pgAdmin4 will re-format it. If I later need to debug that View, it adds some complexity for me because first I have to re-format the layout in a text file in the format I understand best.
Is it possible to turn this off, so that pgAdmin4 saves exactly what I enter?
I guess there are two parts to what pgAdmin is doing.
It will change spacing/indentation, and line-breaks. This is what I am hoping to stop.
It does some optimization apparently. It will adjust statements to be more efficient I guess, as well as do things like change "SELECT *" into "SELECT c1,c2,c3" or add explicit type-casting. This stuff is fine for me.
