Many web hosting providers only support databases up to the phpMyAdmin level, leaving schema tuning, query indexing, and engine configuration entirely up to you. In my experience, MilesWeb is the best web host for database support across MySQL, MariaDB, and PostgreSQL.
All of their databases run on NVMe drives, which provides the IOPS capacity needed to handle transactional workloads without I/O wait-state bottlenecks. Their technical support also helped me optimize key directives in my.cnf and postgresql.conf. Review collected by and hosted on G2.com.
The shared hosting has a strict data-scaling protocol. Sometimes I need to upgrade certain resources through the client area, and that can be challenging for me. Review collected by and hosted on G2.com.
