Improve logging in the sql package

[p-kozlowski]

I encountered issues when debugging why a custom query was failing. The query looked somewhat like

SELECT * 
FROM t1 INNER JOIN t2 
WHERE t1.col1 LIKE '%' || t2.col1 || '%' 
AND t1.col1 = ?;

1. The reason of the syntax error was not logged at all
2. The query argument was substituted with the first '%'

Now we log the error reason and properly escape '%' characters in the query
