I thought about adding the table name in the message but it looks like it's
already
there:
"
Expected corruption message output stdout /(?^:(?^ms:heap table
"postgres\.public\.test", block 0, offset 9:\s+)number of attributes 2047
exceeds maximum expected for table 3)
"
So that your proposal makes sense to me.
