Michael Paquier ade925e169 Use min/max bounds defined by Zstd for compression level ... The bounds hardcoded in compression.c since ffd5365 (minimum at 1 and maximum at 22) do not match the reality of what zstd is able to handle, these values being available via ZSTD_maxCLevel() and ZSTD_minCLevel() at run-time. The maximum of 22 is actually correct in recent versions, but the minimum was not as the library can go down to -131720 by design. This commit changes the code to use the run-time values in the code instead of some hardcoded ones. Zstd seems to assume that these bounds could change in the future, and Postgres will be able to adapt automatically to such changes thanks to what's being done in this commit.
