We would like to migrate our old databases to new postgres server, with the simple backup-restore process. The process run fine without errors but when we're checking the source and the migrated datas as field level, we found the following differences:
For example:
Field type: TIMESTAMP WITHOUT TIME ZONE NOT NULL pg93: 2015-08-28 21:25:07.70 pg10: 2015-08-28 21:25:07.7
Field type: REAL pg93: 2.2 pg10: 2.20000005
When I check the 8.3 pg_dump file, it contains the pg83 correct values.
