docs: fix DATAETIME, access to, and to be function typos

@@ -144,7 +144,7 @@ The information about the columns are compiled from several sources:
 
 Currently all columns are set as NULLABLE as the tables will be used for searching/querying only and users with Viewer role should not be able to modify the tables (ex: insert/delete/update data). However, depending on your environment, you may need to set the mode REQUIRED for the appropriate columns.
 
-We selected the type DATAETIME for all columns with dates and times. However, you could also use TIMESTAMP. As [discussed in the MIMIC-III documentation](https://mimic.physionet.org/mimicdata/time), columns with suffix DATE (ex: CHARTDATE) "will always have 00:00:00 as the hour, minute, and second values. This does not mean it was recorded at midnight: it indicates that we do not have the exact time, only the date". This is also true for other columns such DOB and DOD (patients table).

-The `IF NOT EXISTS` syntax was introduced in PostgreSQL 9.3. Make sure you have the latest PostgreSQL version. While one possible option is to modify the code here to be function under earlier versions, we highly recommend upgrading as most of the code written in this repository uses materialized views (which were introduced in PostgreSQL version 9.4).
