Hello,
I am trying to load about 1.4 billion records into a postgresql table.
The data is in about 100 individual CSV files which I load individually
into the table using the COPY command.
After the data is loaded I perform updates to the data, and this is when
I get errors. Some updates work, some crash.
I am using psql and an SQL script file (update.sql) to perform the
updating (UPDATE table SET field=UPPER(field), etc.).
The errors are all "Server closed the connection unexpectedly"
I have been working on this for just over 1 year now, documenting every
step, and I am still unable to get this to work without it crashing
somewhere along the way.
I am beginning to wonder if postgreSQL is bi-polar.
More information needed, to start:
1) Complete example of the code in the script.
2) Table definition(s) of those being copied into.
3) Sample of the data being copied.
4) The error message(s) generated.
5) Database locale
Any help would be greatly appreciated.
Thank you
