//! PostgreSQL-specific expressions
//!
//! This module provides PostgreSQL dialect-specific SQL expressions.
//! For standard SQL expressions, use `drizzle_core::expr`.

/// Case-insensitive LIKE pattern matching (PostgreSQL-specific)
///
/// # Example
///
/// ```ignore
/// use drizzle_postgres::expressions::ilike;
///
/// let query = ilike(user.name, "%john%");
/// // Generates: "name" ILIKE '%john%'
/// ```
pub fn ilike<'a, L, R>(left: L, pattern: R) -> SQL<'a, PostgresValue<'a>>
