1] Removed alter.sql and merged sql statement from alter.sql with create sql wherever possible so that objects can be create in single statement to ensure that whole operation is atomic.
Code merged for below nodes:
Schema, Table, all constraints.
Nodes do not support executing other sql statements with create statement:
Index node (To ensure that create index operation to be atomic added code to Initiate database transaction manually before creating index object)
Node Excluded (As they do not support executing other sql statements with create statement and also create statement cannot be executed inside database transaction):
Database, Tablespace
2] Fixed typo in databases/templates/databases/sql/9.3_plus/grant.sql
