755-756: Use optional chaining for cleaner code.

Apply this diff to use optional chaining:

-if (results[0] && results[0].value) {
-    tableColumn.asExpression = results[0].value
+if (results[0]?.value) {
+    tableColumn.asExpression = results[0].value

496-523: Consider batching queries to improve performance.

The method executes individual queries for each column when checking for user-defined types and spatial features. For databases with many columns, this could lead to performance issues.

Consider batching these queries or fetching all necessary metadata upfront to reduce the number of database round trips.

Also applies to: 550-561

245-248: Use parameterized queries or escape literals to prevent SQL injection.

The schema and tableName values are directly concatenated into SQL strings without proper escaping, creating a SQL injection vulnerability.

Use parameterized queries or escape the values:

-return `("table_schema" = '${schema || currentSchema}' AND "table_name" = '${tableName}')`
+return `("table_schema" = $1 AND "table_name" = $2)`

And pass the values as parameters, or use the escape method:

-return `("table_schema" = '${schema || currentSchema}' AND "table_name" = '${tableName}')`
+return `("table_schema" = ${this.escape(schema || currentSchema)} AND "table_name" = ${this.escape(tableName)})`

268-270: Use parameterized queries or escape literals to prevent SQL injection.

Same SQL injection vulnerability as above - direct string concatenation without proper escaping.

Apply the same fix as suggested for the table filtering above.

353-358: Add error handling for database queries.

The database queries lack proper error handling, which can cause unhandled exceptions and make debugging difficult.

Wrap the queries in try-catch blocks:

-const [
-    dbColumns,
-    dbConstraints,
-    dbIndices,
-    dbForeignKeys,
-]: ObjectLiteral[][] = await Promise.all([
-    this.query(columnsSql),
-    this.query(constraintsSql),
-    this.query(indicesSql),
-    this.query(foreignKeysSql),
-])
+let dbColumns: ObjectLiteral[], dbConstraints: ObjectLiteral[], 
+    dbIndices: ObjectLiteral[], dbForeignKeys: ObjectLiteral[];
+
+try {
+    [dbColumns, dbConstraints, dbIndices, dbForeignKeys] = await Promise.all([
+        this.query(columnsSql),
+        this.query(constraintsSql),
+        this.query(indicesSql),
+        this.query(foreignKeysSql),
+    ]);
+} catch (error) {
+    throw new TypeORMError(`Failed to load table metadata: ${error.message}`);
+}

220-943: Refactor this large method into smaller, focused methods.

This method is over 720 lines long and handles multiple responsibilities, significantly impacting readability and maintainability.

Break it down into smaller methods such as:

• loadTableMetadata()
• loadColumnMetadata()
• loadConstraintMetadata()
• loadIndexMetadata()
• loadForeignKeyMetadata()
• buildTableFromMetadata()

755-755: Use optional chaining for cleaner code.

The condition can be simplified using optional chaining.
