I think you should only accept "-- " as a signature separator if it is either at the start of the mail or within a quoted text (quoted text: only >, | and ' ' before the signature)

In this, it echoes its own source RFC3673[2] -- the sig is indicated by a separator line, and none of the lines in the SQL comment block is a proper separator line.

Modifying the regular expresion to "-- $", the sql comments are not Signature Blocks.
A question:
What do you prefer? To remove text replies or to not remove signature blocks completely?
In the current implementation, if there is a reply block without signature, between parts with signature blocks, it is removed.
Another possibility is to check only for prefix change (even in the case the signature contains > as a prefix), removing only part of the signature.
I do not see a solution to remove them completely if they contains the common reply characters as part of them, like:
text
"-- " (The " are there only to remark the space)
>This is a "not very good signature block" (I do not know if it is very common, anyway).
