Support for using TEXT fields in secondary indexes and UNIQUE constraints

[fulghum]

Allows TEXT columns in Doltgres to work when used in secondary indexes and in unique constraints. PostgreSQL does not have a concept of prefix lengths and Dolt requires prefix lengths for TEXT columns. This now works in Doltgres because a new Doltgres analyzer rule implicitly fills in a default prefix length in these cases.

Depends on:

• Minor changes for implicit prefix lengths in Doltgres go-mysql-server#2703

Footnotes

1. These are tests that we're marking as Successful, however they do not match the expected output in some way. This is due to small differences, such as different wording on the error messages, or the column names being incorrect while the data itself is correct. ↩
