You cannot add a serial column after table creation time in PostgreSQL.

Dear Pgadmin Folks,

I am using pgadminIII 1.0.2 with PostgreSQL 7.4 under W2K SP4 and Cygwin (current as of 2 or 3 weeks ago). The server is running locally.

If I attempt to add an column of type serial or bigserial to a table, the operation fails with a message telling me that adding an column with a default value is not implemented. What is really weird is that one can, in fact, add a column with a default value, like an int4 with a default value or 0. The problem does not arise if the serial (or bigserial) column is created when the table is created (as a part of CREATE TABLE).

Yours,
David
