4990fc84f1 Only use a Bloom filter on an automatic index if one or more of the key 
columns in the index can take on non-TEXT values.

FossilOrigin-Name: 5916705c731604d2e6b51a307cc8d7b67f4c102062bfdfcbc716a2916e0b0d86

a353369f57 In the Bloom filter optimization, hash all strings and blobs into the same 
value, because we do not know if two different strings might compare equal
even if they have different byte sequences, due to collating functions.
Formerly, the hash of a string or blob was just its length.  This could
all be improved.  Fix for the issue reported by
[forum:/forumpost/0846211821|forum post 0846211821].
