Обсуждение: Question about maximum sizes
I was wondering if you know where I could find specifications on the PostGresSQL 7.4.3 (the one build one used). I have information such as: Maximum size for a database? unlimited (60GB databases exist) Maximum size for a table? 16 TB Maximum size for a row? unlimited in 7.1 and later Maximum size for a field? 1GB in 7.1 and later Maximum number of rows in a table? unlimited Maximum number of columns in a table? 250-1600 depending on column types Maximum number of indexes on a table? Unlimited But I need additional information such as what the maximum size of an actual index name is and stuff like that. Do you know where they might have a more comprehensive guide or documentation that might have this information? __________________________ Eric Lai Software Engineer FCS - SOSCOE Data Modeling Huntington Beach, CA Cell: 213-453-6878 Desk: 714-896-5687
