Unlike EM for SQL Server, there is no vendor developed and distributed
gui client for postgresql. While PgAdmin is probably the first choice,
there are a lot other tools for graphical manipulating postgresql
schema and data. Some of them are windows only, others are available
on different platforms too. See gborg or google for a reference
(There are even sposored links in google if you type in something
with "postgresql")

itsprimary key, and perhaps modify 1 or 2 of its other columns.  With SQL Server Enterprise Manager, I can copy a row
intoa "new row" buffer, modify its primary key to ensure uniqueness, optionally modify 1 or 2 other columns, and paste
theresult into the table. 

alter table ... add column; update ... set newcolumn=oldcolumn;
alter table add constraint ...

WithSQL Server Enterprise Manager, I can copy a set of rows from one table and paste them into another table.

Dont misunderstand me, I also valuate the easy use of gui admin tools,
but I also think a DBA schould have an in depth knowledge of the
database in the first place and be in principle able to handle
all tasks with SQL statements. And as it turns out, some things
(like copy table data between identical tables) is even simpler
with the statement instead of copy and paste.
