PostgreSQL Adapter Project - Code Review 1 Changes

General Research

Task	Status
Can postgreSQL be configured to have the where clause use case insensitive compare for string values? i.e. (select 'Q' = 'q' => should return true)	(DONE) http://www.postgresql.org/docs/8.4/static/citext.html
Add UUID generation to x64 versions
Does extract(epoch from value) return milliseconds?	YES
What encoding (UTF-8 and/or UTF-16) does PostgreSQL use for unicode? Can this be configured per column?	UTF-8
How is a repeatable read with exclusive lock implemented?
Does timestamp'value', handle java.sql.timestamp.toString()?	YES
Does to_timestamp support milliseconds?	YES Precision is up to microseconds(10^-6) http://www.postgresql.org/docs/7.4/static/functions-datetime.html
Does postgreSQL have constants for boolean values?	YES TRUE and FALSE (they are case insensitive)
Does posrgreSQL jdbc driver support returning metadata in UpperCase	NO Since database objects are case sensitive, returning UpperCase would make for corrupt data May be consider changing SQLManager to enforce all database object names to be lowercase
Does renaming a column cause error if a view depends on it?	NO View' is updated with to use the new column name
Does lo.sql unlink large objects when table is truncated?	NO http://www.postgresql.org/docs/8.3/static/lo.html#AEN104018

Classes

PostgreSQLAdapter

Task	Status	UnitTest
Implement setQueryTime with Timer object if code variation is limited, extract to SQLAdapter	DONE
Refactor escaping literals May be make use isLiteral	DONE
appendMatchExpression Add parentheses to enforce operation order Remove implementation of MatchNode.WEIGHT.SYMBOL	DONE
indexNameMatches Use toMetadataCase and toDatabaseCase instead of toLowerCase/toUpperCase	DONE
appendSuffixHint Implement query locking for aggregate queries (i.e. repeatable read + exclusive lock)
appendLiteral Check if timestamp accepts java.sql.timestamp.toString() format If boolean constants are supported, use those instead of string 't'/'f'	DONE
getBind Check if override is necessary
isLiteral Use string.length and binary.getSize to ensure less than 1GB	DONE
appendTypeConversion Ensure to_timestamp accepts milliseconds Ensure case Primitive.TIMESTAMP_ORDINAL: returns milliseconds (extract(epoch from	DONE
isUnicode Check if column is set to use UTF-16 encoding TRUE == is a unicode column FALSE == is not a unicode column null == unknown (e.g. number column or column not present)	DONE
s_bindFactoryArray[Primitive.BINARY_ORDINAL] Use reflection to make use of postgresql jdbc objects and methods to handle large objects	DONE
DUPLICATE_KEY_NAME_PATTERN Modify pattern to remove dependency on english words	DONE
s_bindFactoryArray Use parent BINDS for unchanged binds	DONE

Refactor checking for BLOB column to isBLOB	DONE
Refactor checking for full-text search index on a column to getFullTextIndex	DONE
alterColumn - use this logic execute SQL to drop all dependent view/s for the column's table alter the column create the deleted view/s	DONE
renameColumn - use this logic for check if column has full-text search index rename the column rename column$ drop full-text search trigger create full-text search trigger	DONE
dropIndex call super if index is TEXT index drop column$ drop full-text search trigger	DONE
appendColumnAlternation run UnitTest to check for change in nullness and precision	DONE
renameTable fix full-text search trigger maintainence	DONE
deleteLargeObjects change to use for loop instead of iterator	DONE
getIndexInfo check if override is needed for
Use toMetadataCase and toDatabaseCase instead of toLowerCase/toUpperCase	DONE
