issue with #12: By default, when are the postgres logs rotated on an IBM Netezza Performance Server? per the Netezza System Administrator Guide: By default, the system checks the size of the log file daily and
rotates it to an archive file if it is greater than 1 GB in size. The system keeps 28 days
(four weeks) of archived log files. (Netezza Support can help you to customize these
settings if needed.) Issue with #15: When computing the row size for a table row, what overhead should be accounted for? For every row of every table, there is a 24-byte fixed overhead of the rowid, createxid, and deletexid. https://www.ibm.com/docs/en/netezza?topic=types-calculate-row-size Issue with #16: What is the purpose of the nzstate command? Use the nzstate command to display the current system state or to wait for a particular system state to occur. Issue with #17 IBM Netezza Performance Server drivers for the Go Language can be obtained from which location? reference IBM Netezza Performenance Server Documentaton:
Go language packages are available in a public GitHub repository. If you want to use any package from the GitHub repository, clone it using the go get command. The go get command clones the source code of the package into $GOPATH/src directory on the application system.
