SQL v2: double backslash being ignored in like expression.

[lentil1016]

I found like '%START//END' or like '%START/END' both match 'STARTEND', instead of 'START/END'.
And that's unexpected, like backslash is being ignored in expression.

I can see the codes dealing with \_ and \% cases, why not the \\ case?

sdk-go/sql/v2/expression/like_expression.go

Lines 50 to 57 in 17059e8

	for textIdx < textLen {
	// handle escaped characters -> pattern needs to increment two places here
	if patternIdx < patternLen-1 && pattern[patternIdx] == '\\' &&
	((pattern[patternIdx+1] == '_' || pattern[patternIdx+1] == '%') &&
	pattern[patternIdx+1] == text[textIdx]) {
	patternIdx += 2
	textIdx += 1

Hey @lentil1016 are you able to recreate this with the current code on main? I can't recreate it from your examples. Additionally, if you look in the test files (specifically

sdk-go/sql/v2/test/tck/like_expression.yaml

Lines 6 to 8 in 42a298d

	- name: Exact match (2)
	expression: "'ab\\c' LIKE 'ab\\c'"
	result: true

) we do have some code checking that the \\ is handled correctly.

Maybe you could provide a test case in the format of that file that reproduces the bug you are seeing?
