pglz_decompress()

От

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,
