Simple steps not supported in Direct Query - Postgres

I just had a call with Microsoft support, we don't understand why it stopped working but we found a way to work around this query folding breaking.

I changed my M code from:

//This code was breaking the folding

let
Source = PostgreSQL.Database(Server, DataBase),
dbo = Source{[Schema="public",Item="gl_summary_union"]}[Data],
#"Renamed Columns" = Table.RenameColumns(dbo,{{"YEAR(b.GL_TRXN_CRTD_DATE)", "Year"}})
in
#"Renamed Columns"

========================

To this:

//This code allows Power Bi to fold the query

let
Source = Value.NativeQuery(PostgreSQL.Database(Server, DataBase), "SELECT * FROM public.gl_summary_union", null, [EnableFolding=true]),
#"Renamed Columns" = Table.RenameColumns(Source,{{"YEAR(b.GL_TRXN_CRTD_DATE)", "Year"}})
in
#"Renamed Columns"

The weird thing is that the first code worked for a couple of months!

Thanks vanessafvg  for your help.

Have a great day
