I frequently administer remote servers over SSH, and need to copy data to my clipboard. If the text I want to copy all fits on one screen, then I simply select it with my mouse and press CMD-C, which asks relies on m y terminal emulator (xterm2) to throw it to the clipboard.
This isn't practical for larger texts, like when I want to copy the whole contents of a file.
If I had been editing large-file.txt
locally, I could easily copy its contents by using the pbcopy
command:
Custom format for displaying bytes as kb
, mb
, gb
or tb
.
Response to a few places on the internet: https://productforums.google.com/forum/#!topic/docs/x_T_N-yRUYg And here: https://stackoverflow.com/questions/1533811/how-can-i-format-bytes-a-cell-in-excel-as-kb-mb-gb-etc
Here is one that I have been using:
[<1000000]0.00," KB";[<1000000000]0.00,," MB";0.00,,," GB"
In some cases, it is possible that PostgreSQL tables get corrupted. This can happen in case of hardware failures (e.g. hard disk drives with write-back cache enabled, RAID controllers with faulty/worn out battery backup, etc.), as clearly reported in this wiki page. Furthermore, it can happen in case of incorrect setup, as well.
One of the symptoms of such corruptions is the following message:
ERROR: missing chunk number 0 for toast value 123456 in pg_toast_45678
This almost surely indicates that a corrupted chunk is present within a table file. But there is a good way to get rid of it.
