While converting a mysql database into postgres, I stumbled over the
following problem:
| INSERT INTO a (id, fkid, displayorder, name, description, internal, mimetype,
mimedata, filesize) VALUES (73,6,5, E'Seefeld.rar', E'Seefeld',0,
E'application/octet-stream',decode('5261...0700', 'hex'),311484587);
As the value for "filesize" suggests, this is a very large BYTEA
(formerly: LONGBLOB) entry with about 300 MB. This is untypical, all
other fields are about a couple of MB and don't make any problems.
This very line leads to:
| sfroehli@host:~$ psql dbname < statement.sql
| Password:
| ERROR: invalid memory alloc request size 1073741824
I have not found any configuration directive similar to mysqls
"max_allowed_packet" to increase the buffer size. And besides, I
don't understand, why postgres wants to allocate 1 GB to store
300 MB (which take 600 MB of ASCII text in the decode()-string).
Any idea how to put this into the target database?
