I just stumbled upon this (using postgresql-9.4-1205.jdbc42.jar)
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select count(*) from product where attributes ? 'location_id'");
org.postgresql.util.PSQLException: ERROR: syntax error at or near "$1"
"product.attributes" is a hstore column:
I recall a discussion about this problem a while ago, but I can't find it any more.
While I certainly would expect a problem when using a PreparedStatement I am surprised
that a "plain" executeQuerys() also tries to do parameter replacement.
I have found the suggestion to use exist(attributes, 'location_id') but that is not
an option as that does not use the index on the column.
So what is the state of this? Do we have a way of escaping the ? operator?
I couldn't find anything in the documentation.
