Hello,
The comments in pg_lzcompress.c say that:
* If VARSIZE(x) == rawsize + sizeof(PGLZ_Header), then the data
* is stored uncompressed as plain bytes. Thus, the decompressor
* simply copies rawsize bytes from the location after the
* header to the destination.
But pg_lzdecompress doesn't seem to check explicitly for the VARSIZE(x) == rawsize + sizeof(PGLZ_Header) condition. Is it caller's responsibility to check for this condition before calling pg_lzdecompress(), or does it happen somehow in pg_lzdecompress()?
Thanks,
