[php-src] Issue #14244: pdo_pgsql: question marks seen as parameter placeholders in dollar-quoted string

Issue: https://github.com/php/php-src/issues/14244 Author: outtersg ### Description Dollar-quoting is a PostgreSQL way of quoting strings, and "no characters inside a dollar-quoted string are ever escaped" (see [the official docs](https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-DOLLAR-QUOTING)). pdo_pgsql however sees ? as parameter placeholders (and **replaces them with $1**, $2, etc., when emulating prepares). ### PHP Version PHP 8.2.1 ### Operating System _No response_
