Here is what Marc had to say about insert.patch included in this archive....

  In preparation of finally moving all my 1.0 databases over to a 1.01
  database server, I looked at pg_dump and found that, unless I missed
  something, it didn't *easily* do what I wanted, which was to dump a database
  to a file, and then reload it again on another server (short-term)...but,
  also, there doesn't seem to be any mechanism for dumping the database to a
  file that can be backed up and quickly reloaded again.

  So, I spent the past several hours modifying pg_dump so that it has an extra
  switch for dumping the data in valid 'insert' strings, so that you can
  quickly and easily reload a database.

  So, now the output looks like:

    CREATE TABLE scrap (integer int4, real float4, text text) archive = none;
    insert into scrap values (1, 1, 'text');

  Now, the hard part was figuring out what types are available, so that the
  insert string works properly for char vs numberic data fields. As such, the
  switch statement I'm using in dumpClasses() for this may be missing values
  for numeric fields (I'm using PQftype() to figure out numeric vs non-numeric
  fields)
