No.
pqinsert(1) doesn't support reading from standard input because it needs to
know the size of the file in order to create an LDM data-product. It can get
this information from the operating system for a regular file, but not from
standard input without reading all of standard input into a temporary file. It
would then have to read the file back in to create the data-product.
The "don't overwrite an existing file" is an interesting concept. I don't see
it's connection with the use-case you outlined, however. Can you describe that
use-case in more detail?
