I know that I can't insert a tuple into Postgres > 8192 KBytes long. We
need to store data in a variable length float array which can take up a
total length of greater than this amount. To get around the limit, we
simply insert a zeroed array (which takes up less character space) and
then update the array in chunks specifying where in the array to put the
data.
e.g. INSERT INTO tablename VALUES '{0,0,0,0,0,0, .... }'; to pad the array with zeros (this, of course, has to be
less
than 8192 KBytes)
then
UPDATE tablename SET array1[1:100] = '{123.9, 12345.987, 123454555.87,
.... }'
etc.
This works fine.
Okay, long intro for a short question. When we do a pg_dump and then
restore the database should the COPY contained within the pg_dumped file
be able to handle these long arrays?
