What is the maximum size for a row, a table, and a database?
PostgreSQL FAQOf course, these are not actually unlimited, but limited to available disk space and memory/swap space. Performance may suffer when these values get unusually large. The maximum table size of 32 TB does not require large file support from the operating system. Large tables are stored as multiple 1 GB files so file system size limits are not important. The maximum table size, row size, and maximum number of columns can be quadrupled by increasing the default block size to 32k.
