How to disable read-only mode on a table? (superUser)

[celati Laurent <laurent.celati@xxxxxxxxx>]

Good morning,

I created a new table yesterday. I am superuser and I have all the rights. I had no worries yesterday to make editions on this table.
Today all my fields are in readonly mode. As this post illustrates:

I tried a reboot of the postgres services. But nothing to do. If anyone could help me ?
Thank a lot.
