Hi
We were using named pipe to read dump data from 'pg_dump -Fc' (compressed format) on Windows.
Restore was failing with 'corrupt dump data' error.
Later found that pg_dump was performing 'illegal seek' on pipe to write the data, which was causing corrupt dump.
I've two questions.
1. With tar format ( -Ft ) I see that data is written in serial fashion so we are planning to switched to this format.
Is it safe to use name pipe to read from 'pg_dump -Ft' (tar format) ?
2. On Linux also from strace output of 'pg_dump -Fc' (compressed dump) used with fifo file, I see 'illegal seek' performed on fifo file too.
But restore doesn't have any issues. Is it safe to use 'pg_dump -Fc' with output file as fifo on Linux ?
Thanks
