The output from first post describing the database schema
Was actually from my production machine - a raspberry pi.
The pi hold a db on an usb-disk, which is pg_dump()ed every night and imported to ibm2 history db (the bad one)The schema is identical to the one with trouble - which is a history database
Intended for testing
Hmmm ... schema is evidently the same, but locale seemingly not.
Is it possible this is a locale problem? I did not look closely
at the original data, but I'm suddenly wondering if it could be
explained by misinterpreting the date field order (month-day vs
day-month). Check the datestyle settings on both machines.
regards, tom lane
But most of the output is correct. Like 95+%
I found the bad ones by chance
The pi - keeping only data for 1 day then table exported and truncated every night
(So there is not more than say max 60 records any given day)
Was only involved because I use it to describe the table

Both faulty (ibm2) and correct(tp) are populated with the same pg_dump()- files that r-pi produces every nigth
And for completeness - b info from the pi
