I don't think pgpointcloud supports writing natively as ply? Are you using PDAL? 

If so:

* What do you mean by "digits"? Do you mean digits after the decimal point?
* What was original source data format before it went into pgpointcloud? LAS
* It is possible that the PDAL ply driver could be modified to support overriding the output precision, but some investigation would need to be done into the rply code that PDAL uses to read/write PLY. Quickly looking at the PDAL source. this feature doesn't appear to exist yet.
