some performance tests I was surprised to find deserialization of dimensionally-compressed patches being as slow as decompression of PostgreSQL compressed datums (main storage).\r\n\r\nReading the code I found a useless call to pc_bytes_serialized_size in pc_patch_dimensional_deserialize.\r\n\r\nRemoving the useless call I get a performance improvement of ~60% (deserialization runs in ~1/10 of the time) for a patch with 6.5 millions of points and 8 dimensions of 8 bytes
