If the index marked <literal>INVALID</literal> is suffixed

<literal>ccnew</literal>, then it corresponds to the transient

<literal>_ccnew</literal>, then it corresponds to the transient

index created during the concurrent operation, and the recommended

recovery method is to drop it using <literal>DROP INDEX</literal>,

then attempt <command>REINDEX CONCURRENTLY</command> again.

If the invalid index is instead suffixed <literal>ccold</literal>,

If the invalid index is instead suffixed <literal>_ccold</literal>,

it corresponds to the original index which could not be dropped;

the recommended recovery method is to just drop said index, since the

rebuild proper has been successful.

A nonzero number may be appended to the suffix of the invalid index

names to keep them unique, like <literal>_ccnew1</literal>,

<literal>_ccold2</literal>, etc.
