### What changes were proposed in this pull request? This PR fixes the support for char(n)[], character(n)[] data types. Prior to this change, a user would get `Unsupported type ARRAY` exception when attempting to interact with the table with such types. The description is a bit more detailed in the JIRA itself, but the crux of the issue is that postgres driver names char and character types as `bpchar`. The relevant driver code can be found [here](https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/jdbc/TypeInfoCache.java#L85-L87). `char` is very likely to be still needed, as it seems that pg makes a distinction between `char(1)` and `char(n > 1)` as per [this code](https://github.com/pgjdbc/pgjdbc/blob/b7fd9f3cef734b4c219e2f6bc6c19acf68b2990b/pgjdbc/src/main/java/org/postgresql/core/Oid.java#L64). ### Why are the changes needed? For completeness of the pg dialect support. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
