How to convert "output deleted/inserted into" in MySQL to Postgres

hey guys, I'm kinda new to Postgres and I'm learning it now. I have work to
convert some stored procedures in MySQL to Postgres and I came across an
issue here that I can't solve:

update db.user
set Deleted = 1
, UpdateTerminal = @UpdateTerminal
, UpdateUser = @UpdateUser
, UpdateDate = @UpdateDate
output deleted.CreditTypeID
, deleted.CreditID
, deleted.Amount
into @ReconDeleted
where Deleted = 0
and ClientID = @ClientID;

I think it tried to update a couple of columns in table user and insert
values in other 3 columns into another table ReconDeleted at the same time.
I have issues converting "OUTPUT INTO" and "deleted" items, with my limited
knowledge about Postgres, I don't think we have those in pg. Can someone
tell me how to convert it? Thanks.

PS: it's my first time using this form, nice to meet you guys:)
