* Remove legacy quoteColumnName() utility
Since Mattermost only supports PostgreSQL, the quoteColumnName() helper
that was designed to handle database-specific column quoting is no longer
needed. The function was a no-op that simply returned the column name
unchanged.
Remove the function from utils.go and update status_store.go to use
the "Manual" column name directly.

Since Mattermost only supports PostgreSQL, remove conditional checks
for different database drivers:
- Simplify specialSearchChars() to always return PostgreSQL-compatible chars

- Simplify GetDbVersion() to use PostgreSQL syntax directly
- Remove switch statement from ensureMinimumDBVersion()
- Remove unused driver parameter from versionString()
* Remove MySQL alternatives for batch delete operations
Since Mattermost only supports PostgreSQL, remove the MySQL-specific
DELETE...LIMIT syntax and keep only the PostgreSQL array-based approach:
- reaction_store.go: Use PostgreSQL array syntax for PermanentDeleteBatch
- file_info_store.go: Use PostgreSQL array syntax for PermanentDeleteBatch
- preference_store.go: Use PostgreSQL tuple IN subquery for DeleteInvalidVisibleDmsGms
* Remove MySQL alternatives for UPDATE...FROM syntax
Since Mattermost only supports PostgreSQL, remove the MySQL-specific
UPDATE syntax that joins tables differently:
- thread_store.go: Use PostgreSQL UPDATE...FROM syntax in
MarkAllAsReadByChannels and MarkAllAsReadByTeam
- post_store.go: Use PostgreSQL UPDATE...FROM syntax in deleteThreadFiles
* Remove MySQL alternatives for JSON and subquery operations
Since Mattermost only supports PostgreSQL, remove the MySQL-specific
JSON and subquery syntax:
- thread_store.go: Use PostgreSQL JSONB operators for updating participants
- access_control_policy_store.go: Use PostgreSQL JSONB @> operator for
querying JSON imports
- session_store.go: Use PostgreSQL subquery syntax for Cleanup
- job_store.go: Use PostgreSQL subquery syntax for Cleanup
* Remove MySQL alternatives for CTE queries
Since Mattermost only supports PostgreSQL, simplify code that
uses CTEs (Common Table Expressions):
- channel_store.go: Remove MySQL CASE-based fallback in
UpdateLastViewedAt and use PostgreSQL CTE exclusively
- draft_store.go: Remove driver checks in DeleteEmptyDraftsByCreateAtAndUserId,
DeleteOrphanDraftsByCreateAtAndUserId, and determineMaxDraftSize
* Remove driver checks in migrate.go and schema_dump.go
Simplify migration code to use PostgreSQL driver directly since
PostgreSQL is the only supported database.

Always apply lowercase named parameter transformation since PostgreSQL
is the only supported database.

- Use PostgreSQL jsonb @> operator for access control policy imports
- Simplify buildLIKEClause to always use LOWER() for case-insensitive search
- Simplify buildFulltextClauseX to always use PostgreSQL to_tsvector/to_tsquery
- Simplify searchGroupChannelsQuery to use ARRAY_TO_STRING/ARRAY_AGG
* Remove driver checks in file_info_store.go
Simplify file_info_store.go to use PostgreSQL-only code paths:
- Always use PostgreSQL to_tsvector/to_tsquery for file search
- Use file_stats materialized view for CountAll()
- Use file_stats materialized view for GetStorageUsage() when not including deleted
- Always execute RefreshFileStats() for materialized view refresh
* Remove driver checks in attributes_store.go
Simplify attributes_store.go to use PostgreSQL-only code paths:
- Always execute RefreshAttributes() for materialized view refresh
- Remove isPostgreSQL parameter from generateSearchQueryForExpression
- Always use PostgreSQL LOWER() LIKE LOWER() syntax for case-insensitive search
* Remove driver checks in retention_policy_store.go
Simplify retention_policy_store.go to use PostgreSQL-only code paths:
- Remove isPostgres parameter from scanRetentionIdsForDeletion
- Always use pq.Array for scanning retention IDs
- Always use pq.Array for inserting retention IDs
- Remove unused json import
* Remove driver checks in property stores
Simplify property_field_store.go and property_value_store.go to use
PostgreSQL-only code paths:
- Always use PostgreSQL type casts (::text, ::jsonb, ::bigint, etc.)
- Remove isPostgres variable and conditionals
* Remove driver checks in channel_member_history_store.go
Simplify PermanentDeleteBatch to use PostgreSQL-only code path:
- Always use ctid-based subquery for DELETE with LIMIT
* Remove remaining driver checks in user_store.go
Simplify user_store.go to use PostgreSQL-only code paths:
- Use LEFT JOIN for bot exclusion in AnalyticsActiveCountForPeriod
- Use LEFT JOIN for bot exclusion in IsEmpty
* Simplify fulltext search by consolidating buildFulltextClause functions
Remove convertMySQLFullTextColumnsToPostgres and consolidate
buildFulltextClause and buildFulltextClauseX into a single function
that takes variadic column arguments and returns sq.Sqlizer.
* Simplify SQL stores leveraging PostgreSQL-only support
- Simplify UpdateMembersRole in channel_store.go and team_store.go
to use UPDATE...RETURNING instead of SELECT + UPDATE
- Simplify GetPostReminders in post_store.go to use DELETE...RETURNING
- Simplify DeleteOrphanedRows queries by removing MySQL workarounds
for subquery locking issues
- Simplify UpdateUserLastSyncAt to use UPDATE...FROM...RETURNING
instead of fetching user first then updating

It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
https://mattermost.atlassian.net/browse/MM-53032
```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public
```
https://mattermost.atlassian.net/browse/MM-52079
```release-note
We upgrade the module version to 8.0. The new module path is github.com/mattermost-server/server/v8.
