LibSqlUtils.escape() no-quote guard uses == 1 instead of == -1, leaving some values un-escaped #68

LibSqlUtils.escape() doubles single quotes for values embedded in the concatenated metadata SQL (pragma index_list / index_info / foreign_key_list and related DatabaseMetaData queries).

The early-return guard reads value.indexOf('\'') == 1 instead of == -1. The intent is "return the value unchanged when it contains no single quote", i.e. when indexOf returns -1. With == 1, any value whose first single quote is at index 1 (e.g. x') is returned un-escaped, so the quote closes the surrounding string literal — a correctness/SQL-injection hazard in metadata queries built from such values.

Expected

Values are returned unchanged only when they contain no single quote; otherwise every single quote is doubled.

Fix

Change the guard to == -1.
