Thread: pgsql: Improve performance of float overflow checks in btree_gist
Improve performance of float overflow checks in btree_gist The current code could do unnecessary calls to isinf() (two for the argument values all the time while one could be sufficient in some cases). zero_is_valid was never used but the result value was still checked on 0 in the first position of the check. This is similar to 607f8ce. btree_gist has just copy-pasted the code doing those checks from the backend float4/8 code, as of the macro CHECKFLOATVAL(), to do the work.
