Description

Creating an index on postgres with both order and opclass specified crashes with a syntax error.

index = Index(
    name=indexname,
    fields=['-body'],
    opclasses=['text_pattern_ops'],
)

django.db.utils.ProgrammingError: syntax error at or near "text_pattern_ops"
LINE 1: ...rdered" ON "indexes_indexedarticle2" ("body" DESC text_patte...

This is because opclass is supposed to be inserted before ASC | DESC in CREATE INDEX.
